Title: Enable seeking smush movies when restoring a savegame

This pull requests enables smush seeking.
At movie load it checks every frame, saving its position in the file and if it is a keyframe (subcodec 0 of blocky16).
For the seek code I drew inspiration from BinkDecoder. The only different thing is due to VIMA, which needs some careful handling. I explained how it works in code comments.
