Could Not Dispatch 0.7.0

• The card for a full provider can say which channels hold the connections. With
  Show the channels in use on, off by default, that card gets one centred line for each
  channel on an account that was full in the last 20 seconds: the channel's name and, when
  Dispatcharr's guide has one, the programme on now, left out when it only repeats the name.
  The lines start at 58.5% of the picture's height, so the picture should leave that part
  empty. The list is rewritten after every check, 2 to 10 seconds, and the encoder reads it
  on every frame without restarting. The guide is asked only while an account is full, with a
  two-second timeout; when it does not answer the lines keep the names alone. It needs an
  ffmpeg whose drawtext has text_align, as the Dispatcharr image has.
• Font for the channels in use: a .ttf, .otf or .ttc file inside the data volume
  for those lines. Empty uses the container's sans-serif font.
