RP2040: Only bitbang 0-byte writes
...
The I2C.c for RP2040 included a special case for writes <=2 bytes to match the MicroPython implementation,
however RP2040 does support 1 and 2 byte reads, with only 0 bytes being the exception.

raspberrypi: RTC: Ensure a time is set
...
Until a time is set, the RTC is not running, and rtc_get_datetime()
returns false without assigning to the out-parameter.
In CircuitPython, this would manifest as arbitrary values being returned,
since uninitialized storage on the stack was being converted into a timestamp.

WIPrp2040: Implement IncrementalEncoder
...
Any two consecutive pins can be used for an IncrementalEncoder
Testing performed: Put a synthesized (few hundred counts per second) quadrature signal into GP2/3 and read the encoder out. Performed filesystem operations at the same time to stress test it.
The reasons for not using common_hal_rp2pio_statemachine_readinto are commented on.

rp2pio: Add pins_are_sequential
...
This can be used where the standard API calls for a list of pins, to check that they satisfy the requirements of the rp2pio state machine, e.g.,
```python
def __init__(self, pin_a, pin_b):
if not rp2pio.pins_are_sequential([pin_a, pin_b]):
raise ValueError("Pins must be sequential")
```

I named the property `in_available` because it is similar to pyserial.
However, it indicates the number of words in the fifo, not the number
of bytes.
