Implement bus keep inputs, as documented in C SDK (#134)
When both pull-up and pull-down are enabled, the RP2040 enters a
so-called "bus keep" function, which uses a weak pull to tue current
high/low state of the GPIO.

See for example
https://raspberrypi.github.io/pico-sdk-doxygen/group__hardware__gpio.html#gab6bf9552da32b3dd0a5d0db45d8374fc

Implement RngCore for RingOscillator (#135)
Implement rand_core::RngCore for RingOscillator from the get_random_bit
function. This is not suitable for security purposes so
rand_core::CryptoRng has not been implemented.

PIO support (#74)
Initial implementation of PIO 

Add all of the infrastructure required to include PIO programs and interact with PIO peripheral registers.
This was a massive effort between @devsnek and @henkkuli. It's great that it's now ready to go.
