As Colombia is such an extensive territory and with such a large number of municipalities, I suggest adding the following sublevel to offer greater accuracy when selecting addresses.

I relate the old PR where the first sublevel has already been added. #89 #145

Putting this on hold. The list feels a bit too large for us to maintain ourselves, so I'd love to see if we can get Google to upstream it instead. Please comment on google/libaddressinput#135

More than 2.5 years have passed, and Google has not made any attempt to upstream this data.

The new 2.0.x branch has disconnected us from Google's dataset to allow us to maintain our own version of the data, so I would like to proceed with this MR, if you are still interested.

Unfortunately, we would need to rebuild the files since the format in 2.0.x has slightly changed (you can look at Brazil for an example).
