HT J2K decoding errors

[Michael Orton]

Summary of the bug: decoding Kakadu encoded HT J2K MXF files gives 'unsupported marker' errors, and generates picture errors for (at least) lossless encoded HT.

How to reproduce: Encode Letterboxed UHD content to Format: MXF OP1A, Codec: Kakadu JPEG 2000, Type: RGB 12-bit, Lossless compression, Codestream: HT using Davinci Resolve v18.6.4.
Decode to TIF file using -vf "select=eq(n\,6)" -vframes 1 -pix_fmt rgb24 flags. Errors show up in bottom letterbox black area

Trial decoding back through Resolve gives clean result.
