Parse lextool response and handle errors. #63

Closed bluecamel closed 2 years ago

bluecamel commented 2 years ago

All evening, lextool has been returning errors, but it wasn't initially clear what the issue was because the HTTP status code was 200. I'm not up to date on python 3, so this may be overkill and/or not latest best practice, so happy to change it if there's a better way.

I think this should now be resolved with the reworked pronunciation generation.
