avcodec/sanm: implement STOR/FTCH for ANIMv1

Handle STOR/FTCH the same way the RA1 game engine does:
On STOR, save the next following FOBJ (not the decoded image)
in a buffer; decode it on FTCH.
The RA1 codecs and the fobj handler now take an explicit
GetByteContext in order to be able to replay stored data.

Used extensively by Rebel Assault 1 for e.g. backgrounds and
the cockpit overlay.

For ANIMv2 keep the current system to store the decoded image, as
replaying a FOBJ would not work with codecs37/47/48 due to sequence
violations.
