Have layout react to pin layout field in HardwareDescription

[andrewdavidmackenzie]

RPi pins alternate 1 on left, 2 on right and so on, so 40 is bottom left
Pico physical pins could 1-20 down left side, then 21-40 UP right side, with 40 top right

Thus, for the board layout to be correct, we need to do it differently for RPi and Pico.

We should send the layout as a field in HardwareDescription and then change the layout view to do one way or the other.

I have added this field: PinLayoutScheme in the HardwareDescription for pi_hw, fake_hw and porky in my pico-piglet branch.

@sundaram123krishnan would you like to work on the hardware layout view in this branch, changing how pins are laid out according to that field?

If you do, please try to DRY-up the code, and re-use as much as possible.... maybe just modifying how the row pair using chunks is created...and keeping all the rest the same?

Pi Pico layout using the CounterClockwise scheme

Pi layout, using the Rows scheme

Will do @andrewdavidmackenzie

This would be required prior to announcing/releasing Pico support is working
