Subject: [PATCH] Update badger2040 start sequence for more contrast

This change is taken from the pico-sdk: https://github.com/pimoroni/pimoroni-pico/blob/main/drivers/uc8151_legacy/uc8151_legacy.cpp#L67-L120 and increases the contrast of pictures sent dramatically. It comes with the expense of using way more time when updating though.
