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.

Correctly configure watchdog tick generation (#78)
Fix: The divider for watchdog tick generation is now being set to the
  source clock frequency in MHz, instead of the clock frequency in Hz.
  Watchdog ticks will now be generated at 1 microsecond intervals
