Add --accumulate-attribute to tippecanoe-overzoom (#189)

Browse Source 
* Starting to factor out attribute accumulation into its own file

* Continuing to factor out attribute accumulation

* Reduce duplicate code

* Plumbing the accumulate-attribute option around

* Call the attribute accumulator

* Test that accumulation works

* Add missing #includes

* Don't sort within individual multiplier clusters

Doing so throws off the spatial distribution of the low zooms

* Docs and changelog

* Add comments
