Create multi-release Java build including support for Java 8, but also module info for Java 11, 17 etc

[oliverlockwood]

At the moment, if you build any project that depends on jnanoid under Java 11 or Java 17, you hit this:

[WARNING] * Required filename-based automodules detected: [jnanoid-2.0.0.jar]. Please don't publish this project to a public artifact repository! *

Clearly for now support should still be maintained for Java 8 consumers, but multi-release JARs exist precisely to cover this sort of eventuality.

I'd be very happy to raise a PR to solve this if @davidklebanoff you would be willing to consider this and are still maintaining this project?
