EnviroDIY/ModularSensors: v0.25.0: Styling & Doxygen Code Documentation

• Automated code documentation using Doxygen, now available at https://envirodiy.github.io/ModularSensors/

• Improved C++ code styling elements in every file in the library, to:
  • Better take advantage of the Clang complier and code error linter) tool;
  • Generally follow Clang Format and Google's coding style guides used with cpplint linter), which:
    • includes massive whitespace changes to improve readability while not changing how the code is executed
  • Support Doxygen documentation.
• Encapsulated modem wake check logic into a function and checking for status using a quick AT ping if no other option is available.
  • This will only affect modems/breakouts that depend on a pulse on their wake pin to turn on or off but for whatever reason don't have a separate status pin connected to the mcu.
• Always re-set the pin mode of a sensor power pin before attempting to turn it on.
  • This could come into play when first attempting to power on a sensor before the initial setup if the pin mode on the sensor power pin was set to input by whatever program the mcu had run prior to running ModularSensors code.

• Fixed issue where the Digi XBee LTE-M modem did not wake during normal logging mode to transmit data to the publisher. See https://github.com/EnviroDIY/ModularSensors/pull/309#commitcomment-39786167
