[New-bugs-announce] [issue30077] Support Apple AIFF-C pseudo compression in aifc.py

[Toby Thurston]

New submission from Toby Thurston:

aifc.py fails to open AIFF files containing the compression type "sowt" in the COMM chunk with an "unsupported compression type" error.

This compression type is an Apple specific extension that signals that the data is not actually compressed but is stored uncompressed in little Endian order.  

Supporting it would require a trivial change to allow the compression type as a byte-string and to add a do-nothing _convert routine. 

This would allow aifc.py to be used with AIFF files on Apple macOS.
