MiniMax: Verify MiniMax grids have been corrected copied from CP2K

[AlexBuccheri]

Need some verification that the grid data has been correctly copy-pasted from CP2K. This could be:
a) An application test that parses and asserts on the grid size
b) Put back into CP2K and confirm the results don;'t change
c) Add some checking when parsing in fortran

Already confirmed by GW100 results coming from original CP2K and CP2K linked with GreenX.
