Also add missing attribution for Vasuk and EcoByss

Also fix a bug with wrong sizing for multiple forms.
The last default size encountered was being used, rather than
using the one that matched the default form.

Two things: One, some states were getting simplified
out of existence. Two, states that crossed the -180/180
longitude line were getting projected from the wrong side
of the planet.

Also make some performance improvements: naturals
are sorted by name, instead of being constructed
to be sorted by size. This significantly speeds up
loading, because those objects were expensive to make.

Also fix up the bounds script to delete old files
