Upload a version on hackage

[guibou]

Could you upload a version on hackage? It will ease the use of bindings-gdal with tools such as cabal, stack or nix.

Yeah, that's something that's long overdue. I'll try to do it in the next few days. I need to first make sure the .cabal has proper bounds for all dependencies which might take a while (I'm using nix to build this in my projects so got a bit lazy with that)

@albertov I'd still be very much interested this if you get the chance.
