Model Licensing

[Bainainai]

This line in the README is potentially a very large problem:
"A big shout-out goes to Rhasspy Piper, who open-sourced all the currently available models (MIT License) and to @jozefchutka who came up with the wasm build steps."

The issue I see is the claim that all of the currently available models have been made available under the MIT License.

When I look here: https://github.com/rhasspy/piper

I see this:
"The MODEL_CARD file for each voice contains important licensing information. Piper is intended for text to speech research, and does not impose any additional restrictions on voice models. Some voices may have restrictive licenses, however, so please review them carefully!"

The license listed for hfc_female/medium, the default option in the demo, itself has a strictly non commercial license shown on its model card. In my spot checking, I didn't encounter a model with the MIT License or anything similarly permissive.

So, the readme makes the licensing situation sound like a walk in the park, but when digging into the actual models, it seems to be more of a minefield.
