theoradec: Fix decoding in the presence of GstVideoCropMeta

Browse source 
Store the video info of the internal frame decode width/height
separate to the exposed (cropped) frame info, so that it can be
used for mapping the downstream allocated video frame buffer correctly
when using GstVideoCropMeta.

Fixes playback of files with sizes that aren't a multiple of 16-pixels
width or height.
