pio: Identify state machines via generic parameters.
...
Eventually, the read and write FIFOs need to be split into separate
objects for DMA. To be able to safely rejoin them only when they belong to
the same state machine, the state machine index needs to be encoded into
the type.

pio: Differentiate between uninitialized/stopped/running state machines.
...
Some operations must only be performed in a specific state. For example,
pin directions must not be changed while the state machine is running, as
the operation modifies PINCTRL. The new API makes wrong usage a lot harder.
Also, the code now supports uninitializing state machines to free
instruction space or to select a different function.

Multiple state machines may want to execute the same program (e.g., two

pio: Split PIO into multiple objects that can be moved around separately.
...
One PIO block often implements multiple functions that are used in
different parts of the codebase. Previously, that would be impossible, as
PIO contained all StateMachine instances.
Now, StateMachine instances use atomic operations whenever accessing shared
registers, so they can be used concurrently.

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.
