I have updated the GitHub a lot (changed tones to be less chirpy, fixed
some smalls) and made a couple of samples (see attachment for MP3 and FLAC
of both tone tables, first 16 then 4). Is this good enough to warrant an
official BIP number? I haven't built a decoder yet, but it seems like the
encoder is working properly (looked at Audacity, seems like it is working),
and some people on reddit want to "allow for decoding experiments"

What suggestions do you all have for it?
