* Refactor OPUS encoder for quality and speed. Use OPUS low delay mode (https://www.opus-codec.org/docs/opus_api-1.1.3/group__opus__ctlvalues.html#ga592232fb39db60c1369989c5c5d19a07) * Slightly tweak linear resample function and disable it on 48kHz input * Rewrite OPUS encoder as a struct with some internal buffer * Use OPUS 192Kbps preset by default * Add encoder callback function on a full buffer * Reuse OPUS output buffer * Add write limiter for samples
