New Cog: Distance Between Locations

[Exper1mental]

The general idea is to have a command where you input two locations, and the bot will report back the distance between them. The geocode.xyz API I use for the weather command could likely be reused for this purpose, at least in terms of converting user input into a more computer-readable format (if needed).

I'm mainly thinking of straight-line distance but it could also be cool to add a way to see what the distance would be by road, bike, train, etc. This could then be expanded further into providing estimated travel time and even a link to navigation on Apple Maps, Google Maps, DuckDuckGo, etc.

Examples: !distance "New York, NY, USA" to "Clemson, SC, USA" !dist road "Greenville, SC, USA" to "Central, SC, USA" !traveltime road "Chicago, IL, USA" to "Toronto, ON, Canada"
