Model chooser screen in settings

[soupslurpr]

A screen in settings to download more models from huggingface from the app itself, pick the model that will be used, and manage/delete them. The models would be downloaded from a repo from my huggingface account and the hashes of the files would be checked against hashes included with Transcribro to ensure integrity even in the event of a huggingface server compromise.

There should be a text box at the top of the screen to test the selected model using the Voice Input Keyboard.

The most recommended models would be shown first and there shouldn't be an overwhelming amount of choice for no benefit. Test different model quants to choose enough models for a sensible variety of speed vs accuracy vs multilingualism and clearly communicate those properties in the interface. If needed, there can be a "more models" button that goes to a screen with the other models to keep the list from being too long.

Additionally, there should be an option to import a model from a file which can show up below the ones downloaded from the app but in a separate section to not mistake them from the official ones.
