fix compact to handle empty list or record in column (#15213)
If a table contains an empty list or record in one column and both column
and -e flags are used, then skip that row.

`compact -e` now skips empty values in a column where as before they were
ignored. Example:

 ```nu
[["a", "b"]; ["c", "d"], ["h", []]] 
| compact -e b
```
before

```plain
 #   a         b
────────────────────────
 0   c   d
 1   h   [list 0 items]
```
after
```plain
 #   a   b
───────────
 0   c   d
```

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.
