v1.45.0

Changed

• Bambu Lab printers are no longer polled. The device asked each one for
  its entire state every eight seconds - about 81 KB a minute for two printers,
  for spools that had not moved. The printer already announces a spool change
  by itself, in a message five times smaller, so the device now listens instead
  of asking. Your screen updates exactly as before; the Wi-Fi does a fraction
  of the work.
• The update page puts Install at the bottom of the screen, and scrollbars
  appear only when a page actually has more to show.

Fixed

• Printer connections stopped dropping and reconnecting. A four-second
  read limit added to keep the interface responsive was also cutting off large
  replies, so the device hung up on printers that were answering perfectly -
  once every poll. Four minutes of observation now show none at all, where
  there were four reconnections in two and a half minutes before.
