Better support for analog inputs about gp2040 HOT 4 OPEN

This may be better suited to the MPG library.

maybe use analogue multiplexer to sample multiple analogue inputs with only 1 or 2 ADCs

Hello, GP2040 is an amazing project! Thanks for all your work.
Maybe multiplexer could have an impact on performance but it should work at all for no-fighting games.
It would be perfect to get analog input to use analog joysticks.
Even one for 2D games could be nice.

I have practically zero experience codin and my syntax is likely all wrong, so everything needs to be rewritten. But nevertheless, could this be a simple deadzone check in analog read after setting a shifted mean point of origin?

define Xy(x,y):

  define Xy_deadzonecheck():
     x = 0
     y = ROOT(X(shift)^2 + y(shift)^2)

     if deadzonecheck[x,y] =< 500:
        x = 0
        y = 0
     elif deadzonecheck[x,y] > 500:

I hope the meaning gets through.
Kind regards
