Small adjustment for 3D CRS awareness

Hello @rhugonnet
I was wondering about the new CRS format in the info(). Is the CRS "name" is more common when we have an EPSG code like EPSG:XXXX ? Thanks :)

[rhugonnet]

@marinebcht I'm not sure I understand the question fully.
In short:

• Not all CRS have an EPSG code.
• All CRS have a name.
  Mostly, the code doesn't tell you what CRS it is (you'd have to look up online what the number corresponds to), while the name is human-readable (which is the point of info())

[marinebcht]

@rhugonnet Okay, we had the impression that the EPSG:XXX format, when it exists, was the most common.
Thank you for the explanation !

[rhugonnet]

It is the most common code format, but not a name (not human-readable) 😉

Hello @rhugonnet, following this problem #805 (comment), I retrieved your PR and applied the corrections with the same logic you did here on PC and Vector + tests (did not write the georeferenced_grid_equal test [yet?], only for pc)
I can propose the corresponding PR https://github.com/marinebcht/geoutils/tree/805_pc_info or you can take my commits if you wish to add some more things :)

[rhugonnet]

@marinebcht Perfect, do you want to add this here directly? That's the easiest I think.

Just follow these steps to push on my branch (adding a git merge from your other branch): https://github.com/GlacioHack/xdem/wiki/Work-on-someone-else's-PR

[marinebcht]

Here my branch from yours https://github.com/marinebcht/geoutils/tree/3d_crs_changes_marine (due to direct push error...)
Thanks :)

Will take care of it soon!
