Additional Leaderboard Support

[KyleForan]

Is your feature request related to a problem? Please describe.
Seperate Leaderboard for Advent of Code and similar events.

Describe the solution you'd like
Another message to be sent alongside the good morning leaderboard with a leaderboard embed.
For advent of code, The private leaderboard would be scraped and the top places would be posted.

Describe alternatives you've considered
Additional Leaderboards could be messages in a seperate channel that is edited everyday to avoid cluttering the general channel.

Additional context
Additional or temporary leaderboards could be stored in individual files that could be easily disabled.

This is a really interesting proposal because it has multiple approaches, some more general than others. The simplest approach would be to add some login credentials to the config, and manually program the rendering of the AOC leaderboard. There could be a more general use case, lets say creating a different leaderboard object which will track the AOC leaderboard and then follow the same logic as the current one.
I'd be interested to see what approach you'd like to take.
