Add pom.xml for publishing to Maven Central

[wardev]

Almost all Java dependencies are available through maven central and it would be useful to have czml-writer published there as well. I've added a pom that works with the current source tree.

There are still a few things that the project owner has to do.[1]

• review group, artifact, and version
• publish cs2j.jar on maven central (agi.foundation:compatibility in the current pom)
• publish czml-writer on maven central

Is there any progress on this? I would really like to use your project now that I started using Cesium, and having czml-writer as a managed dependency on the server side would make things a lot easier.

@jvtrigueros no update here AFAIK.

I'd love to help out, you guys are doing great work. This would probably benefit the community :)

Please get these artifacts on Maven Central.

Closing in favor of #170 .

Closing a pull request in favor of an issue, when the pull request attempts to fix that issue, is a bit unusual.

(I stumbled over that issue a while ago, and it had been open in one of my browser tabs for nearly half a year now, with a mental note "Maybe have a look at this". Apparently people would like to use this as a Maven dependency. And I considered to just say: "Apache 2.0 License FTW" 🤷 , fork that whole thing, and publish it. But maybe it could be published in a more "official" form...?)

I would recommend to open a new merge request to do so, It would be very very appreciated to have this library on maven central

[javagl]

@Zudokakikuto One issue here is what the coordinates of that package should be. I could just fork the repo, add the POM, and publish it as de.javagl/czml-writer/3.0.0. And that would be "clean" insofar that this would just reflect the contents of this package. But still, people might have doubts or concerns pulling in this dependency. Having that with a group ID like com.agi would be preferable.
