Lots of cleanup
* Remove YV12 references. It was never fully supported (only libaom), and unlikely to be used.
* Rename yuvSamplePosition to yuvChromaSamplePosition (clarity)
* Remove av1C box from avifDecoder, it is redundant
* Cleanup wording in a few comments
* Add bitDepth and chromaSamplePosition to avifSequenceHeader (internal; for future validation)
* Coalesce some calls to avifBitsRead()
* Rename local variable in avifBitsReadVLC() (suggested by wantehchang)
* Other minor cleanup in obu.c (suggested by wantehchang)
