Presence detection

[FletcherAU]

The current webcam feed includes a presence list generated from our AP API. I've made some changes so it also outputs the data as json so that it can be incorporated into the new site.

{
  "person 1":{
    "groups":[
      "key",
      "guide"
    ],
    "slack":"UID"
  },
  "person 2":{
    "groups":[
      "swarf",
      "3d"
    ],
    "slack":""
  },
  "person 3":{
    "groups":[

    ],
    "slack":""
