[PROJ] Switch to proj-datumgrid-geotiff for PROJ 7 ?

[Even Rouault]

Hi,

I've tried to articulate my latest thoughts about how to switch to
proj-datumgrid-geotiff & organize it in
https://docs.google.com/document/d/1-QK5NkQ9ADJrF66_6VoUcQoRoYoIiFY8CRsg1Y_MMzc/edit?usp=sharing

Feel free to edit/comment directly in it.

We should try to reach to a quick conclusion if we want to have this ready for PROJ 7, as there
will be some bits of development to do. But I think it is the good time to do this.
