Provide module-info.java

[AlexElin]

At the moment this library can't be depend on it as a java module becasue the library neither contain a module descriptor (module-info.java) nor have Automatic-Module-Name: <module name> entry in the library's MANIFEST.MF.

I propose to add module-info.java (becasue the library is java 9+). So, it'll be possible to depend on in the client's module-info.java

Thanks for taking the time to report this issue!

I'm quite busy right now, but I will look into this next week. Unfortunately I'm not quite familiar with module-info.java yet, so I will need to read up on it.

If you know how to do it and have time, feel free to create a Pull request for it. If not, no problem!
