Provides support for reading Polars structs. This allows opening of supported files (jsonl, parquet, etc) that contain rows with structured data. The following attached json lines file([receipts.jsonl.gz](https://github.com/nushell/nushell/files/13311476/receipts.jsonl.gz)) contains a customer column with structured data. This json lines file can now be loaded via `dfr open` and will render as follows: <img width="525" alt="Screenshot 2023-11-09 at 10 09 18" src="https://github.com/nushell/nushell/assets/56345/4b26ccdc-c230-43ae-a8d5-8af88a1b72de"> This also addresses some cleanup of date handling and utilizing timezones where provided. This pull request only addresses reading data from polars structs. I will address converting nushell data to polars structs in a future request as this change is large enough as it is. --------- Co-authored-by: Jack Wright <jack.wright@disqo.com>
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.
