Waggle Dance releases, groupId change and Hive 3 branch switch

[pat...@gmail.com]

Dear WD users,

We've released new versions of Waggle Dance from our hive-3.x branch, which should support hive3 and hive2 compatibility (to a certain degree).
See Changelog and Readme.

Some other updates to the project:
* Due to changes in Sonatype (Maven central repo deployment) we had to review our deployment process and this lead to us changing the groupId and from `com.hotels` -> `com.expediagroup`. This means the artifacts are now in under `com.expediagroup` and we will publish there going forward. The old artifacts should stay available.
* We've renamed the hive-3.x branch -> main and this is now the default branch. This will be actively developed.
* We've renamed the old main branch -> hive-2.x. We won't actively develop this.

If you have a local clone, you can update by:
git branch -m hive-3.x main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a
Or do a fresh clone.

Thank you,
  Patrick (On behalf of WD committers)
