Added clarification for hardware_serial & baud_rate setting

Browse Source 
Per #72 , added clarifications that setting baud_rate may be required on some ESP32 boards (mine is Huzzah32 Feather) or else you will go into boot loop.
Also, added detail to baud_rate setting that some heat pumps require 2400. Mine is MSZ-GL18NA, which only worked with 2400 (not 4800 or 9600). Note, the default swicago library will first try 2400, and then try 9600, if no explicit rate is provided.
