Add alternative grid for JTSK - JTSK03 transform (EPSG:8364)
The definition of EPSG:8364 uses NADCON method for horizontal grid (.las/.los files)
but this format is not supported by PROJ.
UGKK (Slovak Geodetic and Cartographic Institute) provides NADCON .las/.los files here:
https://www.geoportal.sk/files/gz/slovakia_jtsk03_to_jtsk.zip
Additionally UGKK also provides the same grid file in NTv2 format:
https://www.geoportal.sk/files/gz/slovakia_jtsk03_to_jtsk_ntv2.zip
So let's add the NTv2 file the grid_alternatives table so that PROJ can automatically pick it up...
