ffmpeg | branch: master | Tristan Matthews <tmatth at videolan.org> | Fri Jun 13 10:04:45 2025 -0400| [5ea3adfcf92a7e229e740a4853893756b802d664] | committer: Michael Niedermayer

checkasm: add checkasm_check_dctcoef

This is useful for tests that compare dctcoefs which will be either 2 bytes or
4 bytes, depending on bitdepth.
