Add Encoding from WGS 84 / Web Merc

[flippmoke]

Add the ability to perform full encoding of geometry into a tile. This will include the following steps:

• Scaling to Zoom Level
• Data Simplification
• Clipping Data to Tile (with or with out buffer)
• Geometry Correction (should be part of clipping with Wagyu for polygons).
• Encode to buffer

The input for this system should be our geometry.hpp Features, but tooling should be designed in such a way that partial steps could be selected and used by outside libraries if required (to add flexibility).
