Added CCHM Example program
… dual I2C ports Tested with Teensy 4.1. Added check to see if there is overflow in the calculation for the CAL register. It was silently failing if the number calculated was more than 65536.

Hi.
I added a parameter to the constructor that allows the library to be used on boards with multiple Wire ports. I tested it on Teensy 4.1.
Also, I added a member function to dump the registers in the INA220 for debugging purposes.
I fixed a bug in the configuration enums for the gain settings.
I also added a check in the initialization to catch the case where the calibration register overflows 16 bits. I had that happen when I changed the MAX_AMPS to 2, and the microOhms to 10000.
Thanks for contributing this. It works great for me.
