Issue decoding EXR images compressed with DWAB using Imagemagick

[Richard Van Den Boom]

Summary of the bug: I've created an image sequence by converting PNG images to EXR using ImageMagick 7.1.1. If I compress them using PIZ, ffmpeg 5.1.4 can read them well and convert the sequence to a video format. If I compress them using DWAB, I get [exr @ 0x1a80240] decode_block() failed. errors. I tried ffmpeg 6.1 with same results.
It seemed to me that ffmpeg 5.1.4 was able to decode DWAB compressed EXR files. Am I mistaken?

How to reproduce:

% ffmpeg -threads 24 -thread_queue_size 4096  -r 24  -f image2 -i Images/Electra_24fps/Electra-%06d.exr -pix_fmt yuv422p12 -c:v ffv1 -level 3 -slices 24 -context 1 -coder 1 -slicecrc 1  -an -r 24 -video_track_timescale 24  Electra-MASTER_FFV1-24fps.mkv

ffmpeg version 5.1.4, but also with 6.1
built on Slackware-current (self-built, not official)
