  1. Eliminate Dav1dRef usage in dav1d_parse_sequence_header() 

    It's not used by anything, and the data it references is stack-allocated.

  2. Improve dav1d_parse_sequence_header() 

    Creating an entire decoder instance just for some bitstream parsing
is completely unnecessary. We can instead parse the sequence header
directly into the user-provided buffer while ignoring/skipping
other OBU types, with zero memory allocations required.
