* geobuf.input - initial implementation (WIP)
* geobuf.input - fix reading MultiPolygon's
* geobuf.input - don't store invalid bounding boxes in r-tree.
* Use `protozero` lib to read `geobuf` (Initial implementation, not complete!)
* geobuf.input - poring to `protozero`. (TODO: add support for `GeometryCollection`)
* add initial support for `GeometryCollection` + cleanup namespaces
* remove stderr + cleanup + update copyright
* fix GeometryCollection and MultiLineString decoding + add support for standalone Feature and Geometry
* don't use `reserve` as undelying data format doesn't allow for efficient `distance` implementation.
* add geobuf unit test + update test data
* update data
