JNI bindings to PROJ library 2.0

Notable changes compared to 1.0 release:

• The kortforsyningen in package name and module name has been renamed osgeo.
• GeoAPI dependency upgraded from 3.0.1 to 3.0.2.
• Units of measurement dependency upgraded from JSR-363 to JSR-385.
• (For Java 9 and later) module-info.java added.
• Bug fixes.

This release may be the last one supporting Java 8. Unless there are objections from user community, the next release will target Java 11. Issue #65 can be used for discussion if that upgrade would be a problem.

JNI bindings to PROJ library 1.0
