Reduce memory consumption from attribute accumulation (#290)

Browse Source 
* Progress on plumbing a string pool for full_keys through

* More plumbing for key_pool

* Don't keep features with identical locations as multiplier features

* Revert "Don't keep features with identical locations as multiplier features"

This reverts commit 413f0c8024.

* Adjust calculated maxzoom to account for duplicate feature locations

* Update changelog and version

* Add a test affected by the maxzoom change with duplicate locations

* Round the drop rate a little for cross-platform test consistency
