Implementation of digitalFASTread() possibility

[JoJos1220]

I wanted to avoid digitalRead()/digitalWrite() operation within my Project. Therefore I made a split-up of the tick() function - to enable the possibility to read the Encoder-State within my loop function and the usage of a digitalFASTread() Operation and overload it to the tick function directly.

I made successfull Comissioning on ESP32-WROOM by implementing:
encoder.tick(digitalFASTRead(encoderPinB), digitalFASTRead(encoderPinA));
Instead of:
encoder.tick();
And it worked to me perfectly.
My used digitalFASTREAD() function I used is:
/*-----------------------------------------------------------------------------

• digitalFASTRead(): Function to read a GPIO Pin State as fast alternative to digitalRead()

• ---

*/
int digitalFASTRead(uint8_t pin) {
if (pin < 0 || pin >= 40) {
// Pinnumber outside of valid area!
return false;
}

uint32_t bit = digitalPinToBitMask(pin);
uint32_t port = digitalPinToPort(pin);

if (port == NOT_A_PIN) {
// Invalid Pinnumber
return false;
}

// Pointer on GPIO-Register
volatile uint32_t *reg = portInputRegister(port);

// Read Pin State
bool state = ((*reg) & bit) != 0;

return state;
}

Optional Pin Initialization:
The RotaryEncoder constructor now checks if the pins are valid before initializing them with INPUT_PULLUP.
