feat(tiles): show the most important places at coarse zooms (#854)

Show the most important places at coarse tile zooms

conflated.pmtiles' overview and diffed-places.pmtiles now carry each
row's importance, rounded to two decimals, and a tippecanoe feature
filter on it decides what coarse zooms show: the top 1% at z0, four
times as many per zoom above that, and everything from z4 on. Random
dot-dropping is off for these two builds (-r 1); --drop-densest-as-needed
stays as the safety net for oversized tiles.

A per-feature "tippecanoe": {"minzoom": N} would have been simpler,
but with tippecanoe v2.49 it made tippecanoe drop nearly all features.

Part of #713.
