[Proj] Proj-5.0.0 cct path to gridfiles

HI Steve,

If you start by setting the PROJ_LIB variable you should be fine:

	set PROJ_LIB=C:\proj-5.0.0-RC3\proj-5.0.0\nad
	cct +proj=…

At least that should let you work around this for now. You can also define it properly in the Windows settings as a persistent environment variable if you don’t want to set it on the command line each time you open a new terminal-window.

I will investigate why cct doesn’t find the grids. It seems odd to me.
