Speeding up tippecanoe-overzoom (#191)

Browse Source 
* Speed up mvt_value comparison

* Converting repetitive ifs to cases

* More conversions from ifs to cases

* Optimize the always-true filter case

* Don't convert types of attributes without accumulators

* Unordered map seems to be faster than map

* Add missing header

* Fix some warnings

* Fix the warnings better

* Avoid an int->string->int conversion

* Lazily initialize layer key and values maps when actually needed

* More switches from maps to unordered_maps

* Sure, I'll take the microoptimization

* More emplacement

* Save some copies

* Emplaces and moves

* Lazy linear scan of attributes instead of building a map

* Extra printfs, missing header

* Avoid clipping if the input and output tiles are the same

* But do clip if the tile extent is being reduced

* Make sure I'm not constructing std::strings here at runtime

* More worrying about runtime string construction

* A couple more std::moves

* Const references!

* More const references

* Another std::move

* Make the string_value of mvt_value std::optional

* Reserve storage when decoding

* Provision for different mvt_values to share a string pool

* Use the string pool when decoding

* Avoid another string construction

* Try limiting the depth of the search for duplicate attributes

* Revert "Try limiting the depth of the search for duplicate attributes"

This reverts commit 9ec94a15ff.

* Update changelog

* Fix typo noticed during code review
