Initialize an I2C transport to an ATECC508A
Options are:
:bus_name- "i2c-0", "i2c-1", etc. The default is "i2c-1" which frequently works on Raspberry Pis and Beaglebones:address- This is the I2C address of the ATECC508A/608A. The default is 0x60. It is not common to change this address in Nerves devices.
If a transport has already been created to the specified ATECC508A, that transport will be returned. All commands to the ATECC508A are serialized so that they don't interfere with each other.
