REVISION HISTORY
================
v0.12.7 - 2020-07-15
- Fix some bugs on big-endian architectures.
- Fix an error in s24 to f32 conversion.
v0.12.6 - 2020-06-23
- Change drwav_read_*() to allow NULL to be passed in as the output buffer which is equivalent to a forward seek.
- Fix a buffer overflow when trying to decode invalid IMA-ADPCM files.
