Allow to start multiple state machines in sync ( #301 )
...
* add example of synchronized PIOs
* Synchronize state machines using WAIT IRQ instruction
* Use "irq wait 0" instead of "wait 1 irq 0"
This way, the initial value of the interrupt flag doesn't matter
* Start state machines synchronized without IRQ WAIT instruction
* Improve API

* Add an rp2040 specific #[entry] macro.
This macro extends the one from cortex-m-rt by code to unlock
all spinlocks on boot.
* Idiomatic pointer arithmetic
Apply suggestion by @9names, improving address calculations.
(This doesn't change the generated code at opt levels 2 or "z".)
