Remove unused USAC/ADTS code: ff_adts_header_parse() parse the
object_type from a 2 bits field.
See also 696ea1c2236842572df88d573e24a39be3f19c98.

Use ff_adts_header_parse_buf() wrapper to simplify as GetBitContext is
no longer needed (it was introduced for USAC).

Partially reverts 64bb91fd3b5a00a8849531c7e8dd207f2a626096.

Are these 2 changes related ?
if not they are maybe better in 2 seperate patches

They are related in that they both are partial revert of the same commit,
and they both apply to the same code section (so order matter).
I split it into two patches as I think it makes it clearer.
