[Incubator] Application to add PROJ-JNI as an OSGeo Community Project

Mon Jun 14 10:25:20 PDT 2021

Oh fun, and I like the crossword style logo.

Review:
- Changed "OSGeo Community Project" to "None" (pending your application
being accepted etc...)
- Project Types: Geospatial Library
- Topic, Level 1, Level 2, Standards, etc... all look good!
- Core contributors - is there any employer to thank here?
