Add the Pluto map (#1442)

## Description:
Redoing this PR because the previous one was just a mess. ~~Now
everything is in 1 commit.~~ not anymore

I have added the map of Pluto, based on the discord suggestion that has
41 upvotes.

/>

The map looks like this ^

The map doesn't cover all of Pluto, because we simply don't have the
data about the other side. Instead this map covers most of the mapped
area which has high quality height data.
