Added polars struct-encode-json, providing the ability to encode structs as json (#15678)
# Description
This PR introduces `polars struct-encode-json`. This exposes the ability
to encode struct columns as json strings. This is useful when converting
things to formats like CSV that do not support complex types.

```nushell
> ❯ : [[id person]; [1 {name: "Bob", age: 36}] [2 {name: "Betty", age: 63}]]
                    | polars into-df -s {id: i64, person: {name: str, age: u8}}
                    | polars select id (polars col person | polars struct-json-encode | polars as encoded) 
                    | polars collect
╭───┬────┬───────────────────────────╮
│ # │ id │          encoded          │

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.
