async tile fetcher
...
we use cqueues, which is the async framework that lua-http is built
on. we integrate it into the glib event loop rather hackily by calling
the cqueues event stepper ever 20ms from a glib timeout function
overpass has very low rate limits so we handle a 429 response by
sleeping for a random length of time and retrying. This is, also,
a bit of a hack

draw map once only and copy it to screen in on_draw
...
This massively reduces cpu usage, however it doesn't yet work
if we've moved far enough that we'd need to fetch new tiles.
