About MMAudio V2 Text to Audio

Generates audio from a text `prompt`, with `negative_prompt` to steer away from sounds. `duration` runs from 1 to 30 seconds (default 8), `num_steps` from 4 to 50 (default 25), and `cfg_strength` from 0 to 20 (default 4.5). A `seed` between 0 and 65535 makes results repeatable.
