This fork is for adding the ability to interrupt infinite JS loops in client code for my game, Robot Recharge

To build, good luck. The Maven jar task works, but the produced libraries need to be manually inserted into the generated archive. The GH Actions workflow should create all of the native libraries.

To test new builds, first delete /tmp/duktape4j-1.2.1/* to remove old extracted binaries.
