Artem Pavlenko 0253653676 Geobuf.input (#3715)
* 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
