v.0.73.0

Added

• Screen areas. Draw up to eight rectangles on the picture, and the device
  watches them by itself: for a change, for a picture that stops moving, for
  one it has saved, or for a colour. An area can send a notification, keep a
  dashcam clip and show in Home Assistant, and a runbook can wait for one with
  wait area Name. Automation panel. API: /api/v1/regions.
• The touch remote can sit as a bar under the picture instead of floating
  over it: the button at its end docks it, and the console remembers.
• Graphs of the frame rate and the bitrate over the last minute in the Video
  readout. Touch or point at one for the value at that moment.
• A new device asks once what it will be plugged into: a server, a media or
  gaming PC, a Steam Deck, a Switch, an Android TV box. Pick all that fit, or
  skip it. Each device gets a profile with settings that suit it.
• A device that names itself over HDMI-CEC and has no profile yet gets an
  offer to make one. "Never for it" stops the offer for that device.
• The device presets hide the console buttons that make no sense there: a
  Switch gets no keyboard button, a Mi TV Stick (its USB is power only) keeps
  the TV remote and little else.

Changed

• On a phone held upright the picture sits at the top, with the free space
  under it in one piece for the thumb.
• On a phone on its side the bottom bar keeps to one row, the rest goes
  behind More, so the picture gets the height.
• More on a phone is a list with words, not icons alone.
• Settings on a phone: the sections are one row that scrolls sideways, and
  the profile line takes one row.

Fixed

• The search box in Settings, the log and the recordings looked disabled.
• On a phone the Num, Caps and Scroll lights were meant to hide and did not,
  so the bottom bar ran off the right edge.
• A webhook that answered 200 with no length (a plain HTTP/1.0 reply) got
  the same notification again and again: the device took the answer for a
  failure.
• After hours of uptime the stream could switch to MJPEG until a restart.
  The H.264 encoder got rebuilt when the picture turned simple, and the new
  one found no room in PSRAM. Now it is rebuilt only when the room is there.
