[PROJ] ugprade notes for 6.3.1 to 7.0.0

[Greg Troxel]

I just updated my staging pkgsrc package for proj to 7.0.0 from 6.3.1.
As usual I look at what files are added/removed and make sure they are
intended changes.

uninteresting bug fix.  Correct?

This looks like a config file, in which case it's in the wrong place
(etc vs share -- share is supposed to be read only by users).

Also, I see a cache, but not a cache path, and I'm guessing because it
goes in $HOME/.cache for the uid invoking proj.

(Actually, pkgsrc puts config files into /usr/pkg/share/examples/proj
and then copies them into /usr/pkg/etc where the program is expected to
read them.  They are deleted on uninstall and updated if they are
unchanged.)
