This version eliminates the need for the request package.

This release contains no user-visible changes to the code.

olc is now available on MELPA (https://melpa.org).

olc-decode now supports a format keyword arg. The return value for the latlon format has been changed from a cons to a list, which is a breaking change. But since I'm the only one relying on that format (at least for now), that shouldn't matter.

Version 1.3 adds the :compound keyword arg to olc-is-valid, olc-is-short, and olc-is-full, so these functions can be used to recognize (potential) compound codes.

Version 1.2.0 makes the nominatim URL configurable. Geocoding is still limited to the nominatim API, but you can now use a local or paid instance, if you prefer.

Version 1.1 has significantly improved error handling and type checking. Predicate functions have been (mostly) converted to operate directly on the codes without parsing, which improves performance.
