Button clips don't work well, needs re-designing

[MatthewPageUK]

The button should clip into the base, but also needs to be fixed well so they don't pop out when pressed. Temp fix is glue, but I don't want any glued in parts.

Maybe a screw fixing or bracket..

Also please consider flipping the Pico to expose the bootsel button, as the latest nightly builds of micropython allow the bootsel buttonto be used as user input button, (via micropython/micropython#10935). This reduces the BOM by one button, and it's associated wiring.

An example of such usage can be found at https://github.com/samveen/pico-mpy-2fa-totp/blob/main/password.py#L26

Thanks @samveen , that's a really useful feature. I've been working with some 3d printed buttons, this will work well with it..
