Tests missing for MIAF 7.3.6.7 and 7.3.11.4.2 chroma restrictions #26

MIAF restricts clap transforms and grid sizes to be integer multiples of the chroma resolution. This is not checked yet. I have created two test files.

Example (non-conformant) file with 99x99 clap size with 4:2:0 chroma: odd-sized-heic-clap.zip

Thank you for the samples. This is indeed not implemented but will be.

rbouqueau commented 2 years ago

This is being implemented but for AVIF only at this point.

rbouqueau commented 2 years ago

I've implemented it.
