Remove a pin from reporting

[mattjlewis]

First of all thanks for this, I'm in the process of adding support into my Java diozero library.
From what I can see it doesn't seem to possible to either remove a pin from reporting or to change it from digitial to analog reporting. My test case is:

setPinMode(0, OUTPUT);
addDigitalReporting(0);
setSampleInterval(100);
digitalWrite(0, true);
delay(500);
digitalWrite(0, false);
delay(500);
setPinMode(0, ANALOG_OUTPUT);
analogWrite(0, 255);
delay(500);
analogWrite(0, 128);
delay(500);
analogWrite(0, 0);

I can see the correct reports for the digital writes, but the reported values always remain at 0 for the analog writes.
