This test verifies the parser's handling of multiframe JXL files that
have an entropy-encoded permuted table of contents for each frame. The
testcase is actually six JXL codestreams concatenated together, and the
parser needs to be able to find the boundaries.

Adds a fate test for the jpegxl_anim demuxer, that should allow testing
for true positives and false positives for animated jpegxl files. Note
that two of the test cases are not animated, in order to help sort out
false positives.
