> Change LatLonShape encoding to use 4 BYTES Per Dimension

>             Project: Lucene - Core

> {{LatLonShape}} tessellated triangles currently use a relatively naive 
> encoding with the first four dimensions as the bounding box of the triangle 
> and the last three dimensions as the vertices of the triangle. To encode the 
> {{x,y}} vertices in the last three dimensions requires {{bytesPerDim}} to be 
> set to 8, with 4 bytes for the x & y axis, respectively. We can reduce 
> {{bytesPerDim}} to 4 by encoding the index(es) of the vertices shared by the 
> bounding box along with the orientation of the triangle. This also opens the 
> door for supporting {{CONTAINS}} queries.
