Adding websockets to the core script

Ft Add Websockets to Core Script

Changes

• Added websocket publishing of events to the core script. By default websockets are not enabled
• Added 3 additional optional args to the __main__.py file
  • websocket-host, default="localhost"
  • websocket-port, default=8675
  • enable-event-websockets, default=False

QA

• Run the updated section in the README to verify the above changes
• Run other sections to ensure nothing broke and that the server will function without the websockets being enabled

what are you using the websocket for?

@florian-asche great question, I was wanting to create a webpage that could be visited that would subscribe to events and react, say display images or render a 3d model, or really anything, as long as you're listening to satellite events
