split list: add streaming, closure argument, and splitting before/after a separator (#15161)
- this PR addresses most of the points in #13153

# Description

- make `split list` support streaming
- **[BREAKING CHANGE]** if the input is split on consecutive items, the
empty lists between those items are preserved.
  e.g. `[1 1 0 0 3 3 0 4 4] | split list 0` == `[[1 1] [] [2 2] [3 3]]`
- accept a closure as argument, the closure is called for each item, and
if it returns `true` the list is split on that item
- added `--split` flag, which allows keeping the separator items.
`--split=after` splits the list *after* the separator and
`--split=before` splits the list *before* the separator.
  `--split=on` is the default behavior where the separator is lost

# User-Facing Changes

`split list`:
- keeps empty sublists
- allows using a closure to determine items to split on
- allows keeping the separator items with `--split=after` and
`--split=before`

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
