Planetiler update

Some really impressive file-size gains. I just need to test these new planet assets before merging.

# planetiler 0.5
115G    maps-earth-planet-v1.36/maps-earth-planet-v1.36.mbtiles

# planetiler 0.7
86G     maps-earth-planet-v1.40/maps-earth-planet-v1.40.mbtiles

Note that this is also comparing two different planet inputs, so it's not a great test, but the planet build process is so slow that I'm not willing to run a more precise experiment at the moment.

The "small example build" is running out of disk space. I'm pretty sure I'm doing something wrong with the new planetiler API.

This line from the logs is interesting:

+planetiler-build-mbtiles | 0:00:02 WAR - ❌️ 76G storage on / (overlay) requested for read phase disk, 10G available

Trying to allocate 76GB seems like an awful lot for processing Bogota...

I was using a data structure intended only for planet builds. Now we'll optionally use a smaller one for non-planet builds.
