[FEAT] Add Discord Presence Updates for HLL Server Status

[robbmanes]

Is your feature request related to a problem? Please describe.

• Currently, GlowBot does not leverage any presence updates that indicate server presence. It would be useful to get a player count, seeding status, etc.

Describe the solution you'd like

• Status updates to the GlowBot presence, including:
  • Server player count
  • Seeding Status
  • Multi-server support

Idea to present seeding status: the code could collect collect state for all servers. The bot presence string could then display each server status in sequence.
Usable string length is pretty short so there is a challenge in getting all the info in an understandable format.
