b873fa7a5f The zip command. (#3919)
We introduce it here and allow it to work with regular lists (tables with no columns) as well as symmetric tables. Say we have two lists and wish to zip them, like so:

```
[0 2 4 6 8] | zip {
  [1 3 5 7 9]
} | flatten

───┬───
 0 │ 0
 1 │ 1
 2 │ 2
 3 │ 3
 4 │ 4
 5 │ 5
 6 │ 6
 7 │ 7
 8 │ 8
 9 │ 9
───┴───
```

In the case for two tables instead:

```
[[symbol]; ['('] ['['] ['{']] | zip {
  [[symbol]; [')'] [']'] ['}']]
} | each {
  get symbol | $'($in.0)nushell($in.1)'
}

───┬───────────
 0 │ (nushell)
 1 │ [nushell]
 2 │ {nushell}
───┴───────────
```

463dd48180 Flexible dropping of rows (by desired row number) (#3917)
We very well support `nth 0 2 3 --skip 1 4` to select particular rows and skip some using a flag. However, in practice we deal with tables (whether they come from parsing or loading files and whatnot) where we don't know the size of the table up front (and everytime we have these, they may have different sizes). There are also other use cases when we use intermediate tables during processing and wish to always drop certain rows and **keep the rest**.

Usage:

```
... | drop nth 0
... | drop nth 3 8
```

ba483155d7 Reimplement parsers with nu-serde (#3880)
The nu-serde crate allows us to become much more generic with respect to how we
convert output to `nu-protocol::Value`s. This allows us to remove a lot of the
special-case code that we wrote for deserializing JSON values.

* Refactor Hash code to simplify md5 and sha256 implementations

now. Error reporting includues the name of the hash again.

b190051e15 Fix select to insert nulls in sparse tables instead of ignoring absent values (#3857)
Select used to ignore absent values resulting in "squashing" where
columns for multiple rows could be squashed into a single row.

This fixes the problem by inserting null/nothing into absent value, thus
preserving the structure of rows. This makes sure that all selected
columns are present in each row.

111477aa74 Add sha256 to the hash command (#3836)
Hashers now uses on Rust Crypto Digest trait which makes it trivial to
implement additional hash functions.

The original `md5` crate does not implement the Digest trait and was
replaced by `md-5` crate which does. Sha256 uses already included `sha2`
crate.

651d425046 Remove ptree dep from nu-command, remove associated feature. (#3741)
Nothing used the `ptree` feature or optional dependency within
`nu-command` except to include it within the `version` output. This
may be related to when `nu-cli` also had a `ptree` feature, but
I'm not sure.

That leaves the code within `nu_plugin_tree` as the sole remaining
user of `ptree`, which is already covered by the feature `tree`
and included in the `version` output.

bb5ab5d16c nu-cli ctrl-c feature support. (#3718)
