Using I2C to bit bang UART

This requires that the servo be programmed to operate at 100,000 baud. Use a programmer such as my Raspberry Pi Pico script to write 0x013 to register 0x02.

Methods

Function	Address Byte	Data Byte(s)	Total Bytes
read(1)	7 bits + 1	Only 0xFF	2
write8()	7 bits + 0	Must be in form 0b1XXXXXXX, will be output as 0bXXXXXX10	2

NB: the address byte is treated as a regular data byte by the servo.
