@juberti Encoder is almost there, usable but not at decoder level yet. Ran 23 configs across CELT/SILK/Hybrid covering all bandwidths and frame sizes, encoded with both gopus and libopus 1.6.1, scored with opus_compare. 23/23 pass, 11 at zero gap, a few beat libopus, Getting closer

@juberti Decoder passes all 12 RFC 8251 vectors. SILK ones bit-exact at Q=100, CELT/Hybrid 62-99, zero decode errors across 31M samples.

@thesyncim Very cool, like the name. Would be good to compare performance against the test vectors!
