* Port update cells command
Clean up, nicer match statements in UpdateCellsIterator
Return columns flag into HashSet errors
Add FIXME: for update cell behavior on nested lists
* Fix: process cells for Record when no columns are specified
* Fix: address clippy lints for unwrap and into_iter
* Fix: don't step into lists and don't bind $it var
* Add rotate command
* Add rotate counter clockwise
* Fix comments in the code
* Fix clippy warnings
* Fix comment
* Fix wrong step for non even table sizes
* Fix comment for moving through array
* Refactor rotate and have only one command with a --ccw flag for counter-clockwise rotation. By default, rotate is clockwise
* Update usage description
* Add `Find` command
* Complete rustdoc for test `Value` constructors
* Use `Option::unwrap_or` instead of match
* Add `Value::test_filesize` constructor
* Handle searching for terms in `find`
* Fix `find` command signature
* Return multiple elements when `find`ing by predicate
* Do not accept rest parameter with predicate
* Handle `CellPath` in `r#in` and `not_in` for `Find`
* Use `PipelineData::filter`
* Add example test to zip
* Port merge command from Nushell
On top of the original merge, this one should not collect a stream
returned from the merged block and allows merging records.
* Move fetch to extra
* Move byte stream code to a function instead of copying it twice
* Fix formatting issues
* Make fetch a default command
* Fix formatting
* Use only $nu.env.PWD for getting current directory
Because setting and reading to/from std::env changes the global state
shich is problematic if we call `cd` from multiple threads (e.g., in a
`par-each` block).
With this change, when engine-q starts, it will either inherit existing
PWD env var, or create a new one from `std::env::current_dir()`.
Otherwise, everything that needs the current directory will get it from
`$nu.env.PWD`. Each spawned external command will get its current
directory per-process which should be thread-safe.
One thing left to do is to patch nu-path for this as well since it uses
`std::env::current_dir()` in its expansions.
* Rename nu-path functions
*_with is not *_relative which should be more descriptive and frees
"with" for use in a followup commit.
* Clone stack every each iter; Fix some commands
Cloning the stack each iteration of `each` makes sure we're not reusing
PWD between iterations.
Some fixes in commands to make them use the new PWD.
* Post-rebase cleanup, fmt, clippy
* Change back _relative to _with in nu-path funcs
Didn't use the idea I had for the new "_with".
* Remove leftover current_dir from rebase
* Add cwd sync at merge_delta()
This makes sure the parser and completer always have up-to-date cwd.
* Always pass absolute path to glob in ls
* Do not allow PWD a relative path; Allow recovery
Makes it possible to recover PWD by proceeding with the REPL cycle.
* Clone stack in each also for byte/string stream
* (WIP) Start moving env variables to engine state
* (WIP) Move env vars to engine state (ugly)
Quick and dirty code.
* (WIP) Remove unused mut and args; Fmt
* (WIP) Fix dataframe tests
* (WIP) Fix missing args after rebase
* (WIP) Clone only env vars, not the whole stack
* (WIP) Add env var clone to `for` loop as well
* Minor edits
* Refactor merge_delta() to include stack merging.
Less error-prone than doing it manually.
* Clone env for each `update` command iteration
* Mark env var hidden only when found in eng. state
* Fix clippt warnings
* Add TODO about env var reading
* Do not clone empty environment in loops
* Remove extra cwd collection
* Split current_dir() into str and path; Fix autocd
* Make completions respect PWD env var
* Port fetch to engine-q
* Fix check for path as a string
* Add a timeout flag and fix some span issues
* Add a temporary fetch command that returns byte streams. Got rid of async stuff as we're using the blocking feature of tokio
* More tweaks for the bytestream
* Rewrite fetch using ByteStreams
* buffer read on bytes directly

Very often we need to work with tables (say extracted from unstructured data or some
kind of final report, timeseries, and the like).
It's inevitable we will be having columns that we can't know beforehand what their names
will be, or how many.
Also, we may end up with certain cells having values we may want to remove as we explore.
Here, `update cells` fundamentally goes over every cell in the table coming in and updates
the cell's contents with the output of the block passed. Basic example here:
```
> [
[ ty1, t2, ty];
[ 1, a, $nothing]
[(wrap), (0..<10), 1Mb]
[ 1s, ({}), 1000000]
[ $true, $false, ([[]])]
] | update cells { describe }
───┬───────────────────────┬───────────────────────────┬──────────
# │ ty1 │ t2 │ ty
───┼───────────────────────┼───────────────────────────┼──────────
0 │ integer │ string │ nothing
1 │ row Column(table of ) │ range[[integer, integer)] │ filesize
2 │ string │ nothing │ integer
3 │ boolean │ boolean │ table of
───┴───────────────────────┴───────────────────────────┴──────────
```
and another one (in the examples) for cases, say we have a timeseries table generated and
we want to remove the zeros and have empty strings and save it out to something like CSV.
```
