Subject: wavpack: multiple out of bounds memory reads


Fuzzing wavpack led to the discoverey of several invalid memory reads.

global buffer overread in read_code / read_words.c

heap out of bounds read in WriteCaffHeader / caff.c

heap out of bounds read in unreorder_channels / wvunpack.c

heap oob read in read_new_config_info / open_utils.c

All of them have been fixed with a single commit:

Wavpack 5.1.0 has been released and fixes all issues.
