Rostislav Pehlivanov 7b46add725 opus_pvq: do not compile encoding/decoding code if the encoder/decoder is disabled
This should save quite a bit of space if either has been disabled for size reasons.
Could just check if the encoding flag is set during runtime on every single location,
however the overhead of branch misses would somewhat decrease performance.
