Implement bus keep inputs, as documented in C SDK () 
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 () 
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.

b89e728e9c Polishing the USB interrupt examples. 
Answers on a postcard please on how to avoid `static mut` when you have
lazy initialization, and static objects holding references to other
static objects.
