Comment (by gordon):

 I was expecting to see a field named `seq_tier` per
 https://aomediacodec.github.io/av1-isobmff/#codecsparam

 The level parameter value SHALL equal the first level value indicated by
 seq_level_idx in the Sequence Header OBU.

 The tier parameter value SHALL be equal to M when the first seq_tier value
 in the Sequence Header OBU is equal to 0, and H when it is equal to 1.
