Unify inference scripts

[152334H]

There's currently:

• the API (tortoise/api.py)
• the tortoise/do_tts.py script
• the tortoise/read.py script
• the scripts/tortoise_tts.py script
• the app.py webui
• the untouched colab .ipynb

This is too many scripts. Worse still, many of these scripts contain duplicated code to, e.g. split voices or write files.

I want:

• [ ] a meta-inference script that handles all the shared functionality for running tortoise (currently: scripts/inference.py)
• [ ] a single CLI script (most likely cut from tortoise_tts.py)
• [ ] a single webui, that the colab notebook also uses

Everything else should either be scrapped or converted to thin wrappers around the main scripts.

I actually started doing this the other day. I was planning to refactor the code a little before finishing that, but I can do it now if you want.

What do you think of using an external library like Typed Argument Parser?

Depends on how upset you are by the changes I already made earlier

I've never tried it before, if you know it works well then go for it
