demonstrate undefined behaviour in opj_decompress

[pauldreik]

I ran afl and found a few issues. This pull request contains script and data to reproduce it, plus asserts in the code. I used ubuntu 22.04.

I filed issues #1443, #1444 and #1445 demonstrated by this pull request.

To reproduce, build with sanitizers:

sudo apt install afl++
cd tests/fuzzers/afl
./build-afl.sh

Then execute the crash test cases:

xx@xxx:~/code/openjpeg/tests/fuzzers/afl$ build-clang-release-replay/bin/opj_decompress -i crashes/color_1077_1123 -o tmp.bmp

The extension of this file is incorrect.
