Duplicate interfaces for HR mode
spec: Remove intermediate quantized table
fix: legacy lc3_frame_bytes() and lc3_resolve_bitrate()
Cosmetic: rename fast_xxx math function to lc3_xxx
The address offset of the pcm buffer computed is in samples
instead of bytes. This causes the last few bytes of the original pcm
content to get corrupted with the padding bytes.
Pass the number of bytes read instead of samples
as the address offset.
