Who are all these people?!? Aka, popup details

I really like how github gives specific context on people when you hover over their profiles. I'd love to add this & have details like...

- user's timezone
- has the user imported their time from waka.hackclub.com?
- user's top language or editor
- what was their most recent project today & how long ago was the heartbeat for it?

Also, some conditional ones!
- user has the same timezone as you!
- is this the user's first day/week/month?
- if in top 10 on the leaderboard, is this their first time?
- is the user currently hacking? link the repo if detected
- do they have a slack account? link it!
- do they have a github account? link it!
