tidwall 6257ddba78 Faster point in polygon / GeoJSON updates 
The big change is that the GeoJSON package has been completely
rewritten to fix a few of geometry calculation bugs, increase
performance, and to better follow the GeoJSON spec RFC 7946.

GeoJSON updates

- A LineString now requires at least two points.
- All json members, even foreign, now persist with the object.
- The bbox member persists too but is no longer used for geometry
  calculations. This is change in behavior. Previously Tile38 would
  treat the bbox as the object's physical rectangle.
- Corrections to geometry intersects and within calculations.

Faster spatial queries

- The performance of Point-in-polygon and object intersect operations
  are greatly improved for complex polygons and line strings. It went
  from O(n) to roughly O(log n).
- The same for all collection types with many children, including
  FeatureCollection, GeometryCollection, MultiPoint, MultiLineString,
  and MultiPolygon.

Codebase changes

- The pkg directory has been renamed to internal
- The GeoJSON internal package has been moved to a seperate repo at
  https://github.com/tidwall/geojson. It's now vendored.

Please look out for higher memory usage for datasets using complex
shapes. A complex shape is one that has 64 or more points. For these
shapes it's expected that there will be increase of least 54 bytes per
point.

Josh Baker bafb1823b3 Metadata for Webhooks 
Added the `META name value` keyword to the SETHOOK command.

Allows for adding metadata to a webhook. For example:

    SETHOOK myhook http://endpoint/ META m1 12 META m2 13 NEARBY ...

Would result in notification that contain the "meta" element, which is
represented like:

    "meta":{"m1":"12","m2":"13"}

Thanks for the suggestion @amorskoy
