Add JPMS Compatibility (Java 9+)

[mintdaniel42]

This is required because otherwise it is impossible to use this library in a modularized java project. Another option would be to bump the minimum java version to 9 and create a module-info.class file

EDIT: other way would be a multi release jar following this guide: https://www.baeldung.com/java-multi-release-jar

EDIT2: The automatic module name should never ever be changed after 2.6.0 release because it would be a breaking change

Checks failing doesn't seem to be related?

Thank you for this PR.

I understand the issue and the need to have the Automatic-Module-Name line added to the manifest. I will just change this to put it in the Maven release pipeline rather than all the Maven build pipeline.

About the build issue, yes it is unrelated to this PR. I will try to fix that.

@amanteaux it seems not to be working as intended. If you want me to I'll take a look into this
