New plot type: hexplot

[ResidentMario]

There are a couple of space-partitioning plot types in geoplot: quadtree and voronoi. These are both fine options, but there's also a simpler space partitioning plot type, familiar from seaborn, that's more common than these two: the hexplot.

This would be a great addition. +1

Thanks for the great GIS plotting package, it has been very useful.
