Add command !map to display the name and description of the current map

[enigmamf]

A map's description is often helpful to understand what types of locations to expect in a game, especially if one is playing a map with unofficial coverage of various sorts. This PR adds a command !map that:

• Retrieves the current seed's map from the Geoguessr API
• Displays a message with the title, creator, summary, and the number of plays/likes

(I decided to include the creator/# plays/# likes because that helps indicate if the streamer is playing an imposter map)

I did this as an additional API call because unfortunately the seed information only has the map title, not the map description.

Because that extra API call can be slow, I included a cooldown period.

If you're interested in incorporating this, please feel welcome to suggest any changes or make any edits!
