jasper: updated to 4.2.0

4.2.0 (2024-02-05)

Add the JAS_PACKAGING option to the CMake build in an attempt to allow
easier control over rpath settings by packagers of JasPer.
Remove a number of obsolete scripts.
Make some cosmetic changes to the code for the JPC codec in order
to improve readability.
Fix a portability bug related to threads/atomics.
Replace some lingering uses of strtok in the JPC coder with jas_strtok,
since the use of strtok is problematic in multithreading contexts.
