Improve handling of AIFF-C compression type

[AkiyukiOkayasu]

In pacmog v0.4.2, the following AIFF-C compression types were supported: https://github.com/AkiyukiOkayasu/pacmog/blob/80de8c212848956424fe99f4ce177dd0eb305c5b/src/aiff.rs#L72-L77

These types are compatible with most commonly used AIFF files. However, they are insufficient for certain edge cases:

• twos (16bit big endian)
• in24 (24bit big endian)
• in32 (32bit big endian)
• 42ni (24bit little endian)
• 23ni (32bit little endian)

Additionally, there are rare cases where the bit-depth specified in the COMMON chunk does not match the bit-depth assumed by the compression type:

This PR improves the handling of AIFF-C compression types. If the compression type is present and not 'NONE', the bit-depth specified in the COMMON chunk is overwritten with the value corresponding to the compression type.
