v0.2.0

• With a Dispatcharr API key, sends a channel left on the fallback back to its first
  stream. Dispatcharr never leaves the fallback by itself, so a channel whose provider
  came back within minutes stayed on the card for hours while anyone held it.
• The first try comes after two minutes on the card, then 4, 8 and 15 minutes apart while
  the stream keeps failing; the wait starts over once the channel has held a real stream
  for 15 minutes.
• Asks Dispatcharr nothing while nobody watches the card. Without a key, nothing changes.
