New templates for `rat_salsa` and inline TUIs

[JayanAXHF]

1. rat_salsa is a very useful library for builing TUIs with ratatui, particularly the focus widgets and the mouse interactions. I was wondering whether an async template similar to the component template could be made, which uses rat_salsa for components and other actions.
2. Inline TUIs are incredibly useful, and a template on how to make them would be super useful!
