UK Met Office DataHub weather provider

[XBCreepinJesus]

I have created a new weather provider that uses the Met Office's new DataHub API (their existing DataPoint service will eventually be shut down, to be replaced by this one).

I have written this provider to return precipitation as a probability, in line with the existing Met Office provider (although it can also supply absolute values in mm). As such, there needs to be a small addition to weather.js where the if statement checks for the existing Met Office module when returning precipitation units.

The documentation for the weather module will also need to be updated (if approved, of course).

Looks nice on first sight.
a) Could you run npm run lint:prettier and commit the changes? That would fix the tests
b) Do you know when the old API is shut down?

Ok, I've run the prettier script - it just removed a couple of trailing commas by the looks of things. I also replaced the use of config.long with config.lon to be more consistent with existing providers - something I just noticed while looking at the other providers documentation!

As for when the old API is shut down - there's nothing to say at the moment, but it's probably not for a while yet. Some info here: https://www.metoffice.gov.uk/services/data/datapoint/notifications/weather-datahub
