Table content rolling. (#3097)
There are many use cases. Here we introduce the following:

- The rows can be rolled `... | roll` (up) or `... | roll down`
- Columns can be rolled too (the default is on the `left`, you can pass `... | roll column --opposite` to roll in the other direction)
- You can `roll` the cells of a table and keeping the header names in the same order (`... | roll column --cells-only`)
- Above examples can also be passed (Ex. `... | roll down 3`) a number to tell how many places to roll.

Basic working example with rolling columns:

```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8

───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
 # │ bit1 │ bit2 │ bit3 │ bit4 │ bit5 │ bit6 │ bit7 │ bit8
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
 0 │    0 │    0 │    0 │    0 │    0 │    1 │    0 │    0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```

We want to "shift" three bits to the left of the bitstring (four in decimal), let's try it:

```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
| roll column 3

───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
 # │ bit4 │ bit5 │ bit6 │ bit7 │ bit8 │ bit1 │ bit2 │ bit3
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
 0 │    0 │    0 │    1 │    0 │    0 │    0 │    0 │    0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```

The tables was rolled correctly (32 in decimal, for above bitstring). However, the *last three header names* look confusing.
We can roll the cell contents only to fix it.

```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| rename bit1 bit2 bit3 bit4 bit5 bit6 bit7 bit8
| roll column 3 --cells-only

───┬──────┬──────┬──────┬──────┬──────┬──────┬──────┬──────
 # │ bit1 │ bit2 │ bit3 │ bit4 │ bit5 │ bit6 │ bit7 │ bit8
───┼──────┼──────┼──────┼──────┼──────┼──────┼──────┼──────
 0 │    0 │    0 │    1 │    0 │    0 │    0 │    0 │    0
───┴──────┴──────┴──────┴──────┴──────┴──────┴──────┴──────
```

There we go. Let's compute it's decimal value now (should be 32)

```
> echo '00000100'
| split chars
| each { str to-int }
| rotate counter-clockwise _
| reject _
| roll column 3 --cells-only
| pivot bit --ignore-titles
| get bit
| reverse
| each --numbered { = $it.item * (2 ** $it.index) }
| math sum

32
```

90 degree table rotations (clockwise and counter-clockwise) (#3086)
Also for 180 degree is expected. Rotation is not exactly like pivoting (transposing)
for instance, given the following table:

```
> echo [[col1, col2, col3]; [cell1, cell2, cell3] [cell4, cell5, cell6]]
───┬───────┬───────┬───────
 # │ col1  │ col2  │ col3
───┼───────┼───────┼───────
 0 │ cell1 │ cell2 │ cell3
 1 │ cell4 │ cell5 │ cell6
───┴───────┴───────┴───────
```

To rotate it counter clockwise by 90 degrees, we can resort to first transposing (`pivot`)
them adding a new column (preferably integers), sort by that column from highest to lowest,
then remove the column and we have a counter clockwise rotation.

```
> echo [[col1, col2, col3]; [cell1, cell2, cell3] [cell4, cell5, cell6]] | pivot | each --numbered { = $it.item | insert idx $it.index } | sort-by idx | reverse | reject idx
───┬─────────┬─────────┬─────────
 # │ Column0 │ Column1 │ Column2
───┼─────────┼─────────┼─────────
 0 │ col3    │ cell3   │ cell6
 1 │ col2    │ cell2   │ cell5
 2 │ col1    │ cell1   │ cell4
───┴─────────┴─────────┴─────────
```

Which we can get easily, in this case, by doing:

```
> echo [[col1, col2, cel3]; [cell1, cell2, cell3] [cell4, cell5, cell6]] | rotate counter-clockwise
───┬─────────┬─────────┬─────────
 # │ Column0 │ Column1 │ Column2
───┼─────────┼─────────┼─────────
 0 │ col3    │ cell3   │ cell6
 1 │ col2    │ cell2   │ cell5
 2 │ col1    │ cell1   │ cell4
───┴─────────┴─────────┴─────────
```

There are also many powerful use cases with rotation, it makes a breeze creating tables with many columns, say:

```
echo 0..12 | rotate counter-clockwise | reject Column0
───┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────┬──────────┬──────────┬──────────┬──────────
 # │ Column1 │ Column2 │ Column3 │ Column4 │ Column5 │ Column6 │ Column7 │ Column8 │ Column9 │ Column10 │ Column11 │ Column12 │ Column13
───┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼─────────┼──────────┼──────────┼──────────┼──────────
 0 │       0 │       1 │       2 │       3 │       4 │       5 │       6 │       7 │       8 │        9 │       10 │       11 │       12
───┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴─────────┴──────────┴──────────┴──────────┴──────────

Extract .nu-env tests and more granularity (#3078)
The autoenv logic mutates environment variables in the running session as
it operates and decides what to do for trusted directories containing `.nu-env`
files. Few of the ways to interact with it were all in a single test function.

We separate out all the ways that were done in the single test function to document
 it better. This will greatly help once we start refactoring our way out from setting
 environment variables this way to just setting them to `Scope`.

This is part of an on-going effort to keep variables (`PATH` and `ENV`)
in our `Scope` and rely on it for everything related to variables.

We expect to move away from setting (`std::*`) envrironment variables in the current
running process. This is non-trivial since we need to handle cases from vars
coming in from the outside world, prioritize, and also compare to the ones
we have both stored in memory and in configuration files.

Also to send out our in-memory (in `Scope`) variables properly to external
programs once we no longer rely on `std::env` vars from the running process.
