What parameters need to test/check for subset compliance?
If one or more of the following statements is true the stream is NOT subset.
sample size in bits = not (8 or 12 or 16 or 20 or 24)
or
min_partition_order > 8
or
max_partition_order > 8
or
min_prediction_order > 12 and samplerate <= 48000
or
max_prediction_order > 12 and samplerate <= 48000
or
frame_size > 4608 and samplerate <= 48000
or
frame_size > 16384
