Maven source build

[belohnung]

Please publish a source jar to your maven repository, so its possible to download it in IDEs like IntelliJ for easier debugging :)

Sorry for not responding in quite a long time 😅

We're not maintaining this library that actively (just when we need changes for our internal needs) and publishing to our own repo was just meant to be an intermediary step but we haven't ever shipped it to OSSRH. We might change that sometime soon as we are continuing to improve on it internally but I can't promise anything yet, as it's not on our priority list.
