An initial version of tz geolocation data pipeline
An initial version of the reference tz geolocation data pipeline using
OpenStreetMap / timezone-boundary-builder data. All code executes on
host to produce data files (currently) in prototxt format for easy
debugging.
Numerous improvements will be made, and extra steps added in follow-up
commits, but this is sufficent to obtain data and serve as a "V1" with
regression tests which can act as a baseline for future changes. More
tests can be added as issues are found or performance enhancements made.
Two basic "debug" tools have also been included to help understand the
intermediate data produced by the pipeline.
