General testing of latest build

[gskjold]

There have been some strange problems lately that have kept me busy in the code, so I have done a number of changes/improvements along the way. Would like to have some more people running this for a day or two before releasing.

If you install this firmware, please let me know your country, type of device and meter manufacturer.

• General optimizations
  • Moved all static strings to progmem to reduce use of heap memory
  • Split larger methods into multiple small methods to reduce use of stack memory
  • Use float instead of double for faster calculations where possible
• Improved firmware upgrade
  • Increased timeout to improve chance of upgrade via URL
  • Store expected firmware version and show warning in system page if upgrade was unsuccessful
• Dynamic RX buffer on HAN port
  • Keeping track on successful reads vs RX buffer overflow, increases buffer if necessary
• Improved debugging
  • Debug info if loop() method spends more than 2000ms on a single loop
  • Additional warning on several methods used in loop if they spend more than 1000ms
• Fixed filter on SSID to allow wider range of characters
• Fixed reboot loop after uploading config file on ESP32
• Improved handling of error codes from price API
• General changes along the way

See code changes here: v2.2.13...master

Fixed filter on SSID to allow wider range of characters

Confirmed on Kamstrup in Denmark on a 8266 board. Everything else seems to be working fine!
