Manuel Lauss d311382c38 avcodec/sanm: fix issues with FTCH offset hack ...

Just add an extra x/y offset parameter pair to process_frame_obj(),
and store the size of the data to FTCH in a separate context member.
The only valid sizes for FTCH are 6 and 12, reject any other.
Finally, if a FOBJ uses codecs37 and above, enforce it to be subversion 2,
to use the simpler STOR/FTCH method.

Fixes BIGSLEEP-440183164/process_ftch.anim
