0.2: OMG JavaScript!!!1!!1!

There's now a JavaScript API worthy of your attention. The demo code has been moved to https://github.com/dhdaines/soundswallower-demo, and has been updated to be all "modern" for whatever that's worth. No, it's worth something, because asynchronous JavaScript is genuinely cool. Also of note, JavaScript defaults to float32 input because that's What the Web Wants.

A major bug in the Python and C API was fixed which broke long utterances such as used in ReadAlongs. The documentation has also been greatly improved, go see it at https://soundswallower.readthedocs.io/

Also the default acoustic model is now the narrow-band one, so as to be more robust to whatever crappy audio you throw at it, and we include also a French model (qui marche plus ou moins au Québec, désolé).
