ESP32 pcf8574 and pcf8575 - library - allow different pins

- Update PCF8574 and PCF8575 library to be able to change SDA SCL pins easily.

- Using wire.h library - allow different pins.

- For example, if you take a closer look at the Adafruit BME280 library, you’ll find out that you can pass your own TwoWire to the begin() method. Do similar with the PCF8574 and PCF8575 libraries.

- Post updates on GitHub

- Add example on GitHub for specifically the esp32cam board - using pins 12 and 2 (or pins that work) - (must not use pins UOR and UOT - I want to be able to plug esp32cam via cable to my desktop - and I need those pins).

- I will test on esp32cam

- with this code - something like this...

- but below code may need to be updated to work...

#include "Wire.h"

#include "Arduino.h"

#include "PCF8574.h"

TwoWire I2Cone = TwoWire(0);

PCF8574 pcf8574(&I2Cone, 0x38);
