New object-oriented WKT2 CRS model introduced (including for GEOGCRS, PROJCRS, VERTCRS, COMPOUNDCRS, BOUNDCRS, ENGCRS, PARAMETRICCRS) with all components. The WKT2 reader has been fundamentally implemented and now supports parsing into the new model as well as conversion to/from ProjNet objects. A new writer enables serialization back to WKT2. Extensive unit tests for parsing, roundtrip, and model structure added. This enables complete, roundtrip-capable WKT2 parsing and serialization in ProjNet for the first time.

References #83 and #86
