Library is in low-maintenance mode

[joshka]

Hey all, I haven't worked with Java in more than 2 years now, and so my inclination to maintain this library is severely lacking. I won't be releasing any further versions of this library (unless I happen to start working in Java again). Feel free to fork this library (noting the license conditions which are fairly minimal)

I'm happy to link to a library maintained by a developer with a reasonable existing presence in the Java world (to avoid mishaps like the recent xz fiasco) and do the various needed things to point at the new library / namespace.

FWIW It looks like JUnit 5.11 may have introduced some neat conversion attributes that could be worth looking into.
