Datum grid package for PROJ

The datum grid package for PROJ contains shift grids for horizontal and vertical coordinate transformations. The PROJ-data package includes all grids and other resources previously tracked by the proj-datumgrid series of packages as well as some new grids. All grids in the PROJ-data package have been converted to the new Geodetic Tiff Grid (GTG) format introduced in PROJ with RFC4.
