https://github.com/nushell/nushell/pull/8379 removed the `-i` flag from `get` and `select` because the new `?` functionality covers most of the same use cases. However, https://github.com/nushell/nushell/issues/8480 made me realize that `-i` is still useful when dealing with cell paths in variables. This PR re-adds the `-i` flag to `get` and `select`. It works by just marking every member in the cell path as optional, which will behave _slightly_ differently than `-i` used to (previously it would suppress any errors, even type errors) but IMO that's OK.
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.
