Content mostly unchanged since v9.9
This update is "minimal" in that it mostly reflects the removal of the 'area'
table, replaced now by 'extent', 'scope' and 'usage'
Other new aspects of EPSG v10 are left aside.
Relates to https://github.com/OSGeo/proj-datumgrid/pull/65 ,
https://github.com/OSGeo/proj-datumgrid/issues/22
As EPSG has no entry for it, we create a grid_transformation, as well as a
dedicated area of use based on the extent of the grid, under the PROJ authority.
With the hope to be able to remove it once EPSG has an entry...
This work mostly consists of:
- a C++ implementation of the ISO-19111:2018 / OGC Topic 2
"Referencing by coordinates" classes to represent Datums,
Coordinate systems, CRSs (Coordinate Reference Systems) and
Coordinate Operations.
- methods to convert between this C++ modeling and WKT1, WKT2
and PROJ string representations of those objects
- management and query of a SQLite3 database of CRS and Coordinate Operation definition
- a C API binding part of those capabilities
