Add a variety of new tests including additional edge cases.

- As always some of these have `is_valid = false`. - `test_000013`: Uses non-required trimmed samples. - `test_000097`: Uses a mono audio element and 32 bit=depth LPCM. - `test_000098`: Uses two layers and 32 bit-depth LPCM - `test_000116`: Places reserved OBUs at various spots within the bitstream. - `test_000117`: Uses `obu_exension_header`. - `test_000118`: Has a mix presentation which is valid in the "additional" profile, but not the "primary" profile. - `test_000124`: Has two sub-mixes. - `test_000125`: Uses a reserved `headphones_rendering_mode`. - `test_000126`: Has a reserved loudness layout. - `test_000127`: Has a mix presentation with too many audio elements for simple profile. - `test_000128`: Has a mix presentation with too many audio elements for base profile. - `test_000131`: Contains a loudness layout reserved in simple profile, but not in base-enhanced profile. - `test_000500`: Mixed-first order ambisonics using FLAC. - `test_000501`: Uses a single reserved OBU. - `test_000502`: Has 0 sub-mixes - `test_000503`: Uses the reserved fields in `info_type`.
