Severe macro-coditioning compilation errors due to enum implementation of binary constants

[GiorgosXou]

Replacing all constant B01... with 0b...-literals should solve the issue for "Arduino Mbed OS Nano Boards" for now. the issue is tracked here: arduino/ArduinoCore-mbed#894 (discord crossref link)

Eg. Compiling the MNIST-example results on every optimization to get enabled:

I could test if detecting predifined B00000000 exists at all and then if not, fallback somehow to literal-ones by appending a 0 to the _X_OPTIMIZE value (so it becomes 0B...) and then add conditions for 0B..s too or something....
