Missing #undef #11
Description
When compiling this sketch on Arduino Nano 33 BLE...
#include "ArduinoEigen.h"
void setup() {}
void loop() {}...I get the following errors:

So I guess ArduinoEigen/ArduinoEigenCommon.h should also undef D0, D1, D2, D3.
Additionally, in the past, I am quite sure I saw conflicts with A0 and A1 (I don't remember on which board). So you might want to also undef A0 and A1 to be on the safe side.
