Check for COC and QCC markers that are not in first tile-part of a tile #213

Closed bitsgalore closed 8 months ago

bitsgalore commented 8 months ago

Clause A.6.2 (COC marker) states that :

If there are multiple tile-parts in a tile, and this marker segment is present, it shall be found only in the first tile-part (TPsot = 0).

And likewise A.6.5 (QCC).

Also applies to COD, QCD, and RGN markers!
