lambda function not in IRAM about ai-esp32-rotary-encoder

[igorantolic]

Would you improve the code and then I can merge.
Obviously you know how so we can improve.

@paul303 can you share your implementation?

I encountered the same-- example still has this flaw. Just do not use the lambda. Use a separate function defined with IRAM_ATTR:

void IRAM_ATTR readEncoderISR()
{
  rotaryEncoder.readEncoder_ISR();
}

void setup()
{
  rotaryEncoder.setup(readEncoderISR);
}

All examples are updated to include the same solution. Additionally, button functions changed.
