Added Jitpack Support

[Taskeren]

This PR adds the jitpack support for your excellent work, so that developers want to integrate with productivemetalworks can use jitpack to include it, which can also provide source jars.

But even with this, there's still something not working, because productivelib is also missing, and your repository seems not updated to the latest version that you released. Can you please update it? And I'll open another PR for jitpack in that repo.

For developers who want to include this project, you need to exclude the productivelib somehow, like:

compileOnly("com.github.JDKDigital:productivemetalworks:VERSION") {
    exclude group: "local.libs"
}

is this better than CF maven?

[Taskeren]

Yes, CF maven cannot provide source jars unless you do upload them along with the releases.
Without source jars, there are many essential features in IDE (IDEA specifically) don't work.

how does Jitpack solve this? I don't make releases on GitHub

[Taskeren]

Jitpack will run publishToMavenLocal and save the built jars to its internal storage when there is request, which these files are used for distributing.

[Taskeren]

And except the releasing tags (or git tags), you can also use commit id and branch name (the latest commit of that branch) as the artifact version.

try it out, I updated the lib repo so you can make a pr
