Scale the tile size limit up with the multiplier at low zooms (#192)

Browse Source 
* Scale the tile size limit up with the multiplier at low zooms

* Add a test to demonstrate that high zoom tiles can't be extra large

* Update changelog and version

* Fail more cleanly when a tile can't be made small enough

* Guard against a cluster where the start marker has been dropped

* Look harder for a working feature interval instead of giving up

* That change to the drop-smallest logic changed a test output

* Update changelog

* Add explanatory comment
