Use upstream `org.reflections`

[BenjaminAmos]

Currently gestalt depends on a custom snapshot of what was org.reflections:0.9.12, re-named to org.terasology:reflections:0.9.12-MB. I do not know the exact reasons for the fork but MovingBlocks/reflections only contains a single unique commit with minor code changes. The README claims that the project is unsupported but things appear to have changed since then, with several upstream org.reflections releases being made, up to the most recent org.reflections:0.10.2. It might be worth upgrading to the upstream source to benefit from any bugfixes that might have occurred since then.

This is mostly an obsolete issue with gestalt 8 (develop branch), since it doesn't rely on reflections anymore. Terasology and Destination Sol could still be relying on gestalt 7 for some time to come though.

I'm not finding all my notes, but here's what I remember of the last time I looked at this:

At the time, I think there had been some newer reflections release, at least 0.9.12. But looking over the bug reports, it was clear there were some problems, and trading my then-problems for different problems didn't seem worth it.

If that was sometime around MovingBlocks/Terasology#4564 , then it was before the upstream 0.10.x releases came out. Maybe those are better?

I think by then (October '21), it was long enough after the v8 work had started that I hoped v8 would be released before I had to worry about Reflections versions again.
