NOTE: THIS METHOD MUST BE CALLED BEFORE ANY I2C REQUEST IS MADE
This method initializes Firmata for I2c operations.
It allows setting of a read time delay amount, and to optionally track
the pins as I2C in the appropriate response table.
To track pins: Set the pin_type to ANALOG or DIGITAL and provide the pin numbers.
If using ANALOG, pin numbers use the analog number, for example A4: use 4.

:param read_delay_time: an optional parameter, default is 0

:param pin_type: ANALOG or DIGITAL to select response table type to track pin numbers

:param clk_pin: pin number (see comment above).

:param data_pin: pin number (see comment above).

:return: No Return Value
