Add basic CLI

[akx]

kittentts --output output.wav --text "This high quality TTS model works without a GPU"

[bencevans]

To run with uv:

uvx --from git+https://github.com/akx/KittenTTS.git@cli \
    kittentts --output output.wav --text "This high quality TTS model works without a GPU"

Thanks for adding @akx, made it real quick to try this out! Something that would be real cool is ability to specify --output - to write to stdout to do something along the following lines. Although may need a --format option too to direct.

uvx --from git+https://github.com/akx/KittenTTS.git@cli \
    kittentts --output - --text "This high quality TTS model works without a GPU" | ffplay -autoexit -

@bencevans Sure! Added a commit that lets you kittentts --output - --text "This high quality TTS model works without a GPU" | play -t wav - (if you have sox; your ffplay -autoexit - works too).

Potential extension: https://github.com/Mic92/kitten-say/blob/ecbbbfdb5ec6c947ee555a18536072039af7bab4/src/kitten_say/cli.py#L63

This will play the sample.
