The issue is that AOT 45 isn't defined anywhere, and looking at the git
blame, it seems to have sprung up through a reordering of the enum,
and adding a hole.
The spec does not define an explicit AOT for SBR and no SBR, and only
uses AOT 42 (previously AOT_USAC_NOSBR), so just rename AOT_USAC to
it and replace its use everywhere.

This makes it far easier to figure out which AOT belongs to which
profile.
Also, explicitly highlight the holes.

This allows users to determine whether a stream is USAC or not.
