This PR is a fix for Issue #725 to allow using the GPIOs>32 (typically for RP2350B variant). This pull request updates the SPI PIO initialisation functions to improve support for higher-numbered GPIO pins and 64-bit pin masks.
The main changes involve switching to 64-bit versions of pin mask functions and correcting the logic for bypassing input synchronisation on the MISO pin.
