9c0db7cae3 Improve HCA/clHCA key detection
- Only test keys when file is encrypted
- Add clHCA_TestBlock to test a frame with the current key
- Move some key detection code to hca_decoder.c and simplify hca.c
detection
- Decrease number of test frames due to increased accuracy of
clHCA_TestBlock

fd52fe0e95 Clean clHCA lib 3 (API)
- rename clHCA_DecodeSamples16 to clHCA_ReadSamples16 since it isn't
really decoding
- divide clHCA_Decode into clHCA_DecodeHeader and clHCA_DecodeBlock to
clarify usage
- unify clHCA_IsOurFile0/1 since one would need to call
clHCA_DecodeHeader right after it anyway
- add clHCA_SetKey for easier key handling
- adapt vgmstream wrapper

43764d6c8d Fix HCA num samples/looping [Binary Domain (PC), Octopath Traveller]
Decoder has been modified a bit so it's easier to feed an arbitrary
number of discard samples (or at least, easier for me to understand),
since encoder delay can be >1024 (frame size) and would make some calcs
go all wobbly

d644d2f9f7 Add HCA key detection and key list
Updated the meta a bit so it's closer to others and optimized some
mallocs, as it was a bit hard to understand for me so I hope it's for
the better
