[Talk-GB] Tools for adding postcodes from Code-Point Open

[ndrw6]

I've added a tool converting postcodes from Code-Point Open to a format 
(.osm) that can be used in jOSM. Optionally the converter can filter out 
existing postcodes, or only output postcodes that do not exist in OSM 
and are located near an OSM building.

https://github.com/ndrw6/import_postcodes

The repository contains pre-generated .osm files and instructions on how 
to use them.

Cheers,
