Fast processor read() delay

[palmerr23]

Thanks for the library, it works well!

To answer the question embedded in the code at line 135 in the cpp file, you do not need the delayMicroseconds(1) for a Pico running at 240MHz (PD_SCK is 500nS) in _shiftIn( ) or read( ).

The delay( ) treatment should probably be the same in both places.

It would be useful, however to have an option, as a Teensy 4 and other processors running at > 500MHz are likely to need them in both read( ) and _shiftIn( ).

  while (m > 0)
  {
    //  delayMicroSeconds(1) needed for fast processors?
    digitalWrite(_clockPin, HIGH);
    if(_fast_processor)
	delayMicroseconds(1);
    digitalWrite(_clockPin, LOW);
    if(_fast_processor)
	delayMicroseconds(1);
    m--;
  }

BTW, I tested the B input and it seems fine.

A pull request will be forthcoming.

I hope this is useful.
