Reduce maxzooms being guessed a little: (#2)

Browse Source 
* Reduce maxzooms being guessed a little:

* Use 1.5 standard deviations, not 2, as the minimum distinguishable
* Give overlapping polygons and linestrings more distinct indices

* Add another drop rate guessing options, from the same metrics -zg uses

* Guard against using -rp without -zg

If you use `-rg`, it will guess a drop rate that will keep at most 50,000 features in the densest tile.
You can also specify a marker-width with `-rg`*width* to allow fewer features in the densest tile to
compensate for the larger marker, or `-rf`*number* to allow at most *number* features in the densest tile.
If you use `-rp` with `-zg` or `--smallest-maximum-zoom-guess` it will choose a drop rate from the same
distance-between-features metrics as are used to choose the maxzoom.
* `-B` _zoom_ or `--base-zoom=`_zoom_: Base zoom, the level at and above which all points are included in the tiles (default maxzoom).
If you use `-Bg`, it will guess a zoom level that will keep at most 50,000 features in the densest tile.
You can also specify a marker-width with `-Bg`*width* to allow fewer features in the densest tile to
