test(openexr): add HTJ2K compression tests for OpenEXR 3.4

Added HTJ2K compression tests when OpenEXR 3.4.0 or newer is
available, and add expected output for the `htj2k32` and `htj2k256`
compression modes.

Created a new reference file `out-exr3.1.txt` for idiff when OpenEXR
version is older than `3.4.0`.
