Check if all tile groups are received in order.

Check the following bitstream conformance requirement in Section 6.10.1
of the AV1 spec:

  It is a requirement of bitstream conformance that the value of
  tg_start is equal to the value of TileNum at the point that
  tile_group_obu is invoked.

This requirement means the tile numbers between consecutive tile groups
of a frame should be contiguous, i.e., monotonically increasing with no
gaps.
