Added clarification for hardware_serial & baud_rate setting #89

Closed anth-dinosaur closed 1 year ago

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.

I tweaked this PR slightly as another user had noticed problems with ESP32 platforms.

Could this please be put into master. I was having the same problem on ESP32 and it took me a good while to find this and figure out I had to specify the baud_rate.
