Pull in "geoarea" code? #1

Nice work here Mike! Reminded me of my long abandoned attempt at geoarea, which would still be useful to have somewhere. If it helps, the code still lives at https://codeberg.org/hypertidy/geoarea, with pure C routines for faster area calcs than anything else, in same forms as geodist, including Karney-algo precise form plus way faster Haversine and Cheap-dist forms.

That's neat, thanks for the reminder! I'm probably 90% sold on terra, while keeping it at arm's length. It's good for sharing illustrations but I don't really want it front and centre of real work. Maybe I can factor terra out with geoarea here 👌
