Helper function to configure whole GPIO in one line

Native Pico SDK timing Uses 32-bit microseconds (same approach as Arduino-pico) for efficiency on Cortex-M0+/M33

ini_getl() * \param Section the name of the section to search for * \param Key the name of the entry to find the value of * \param DefV

Format byte count with units.

Poll function that is called every few milliseconds. Can be left empty or used for platform-specific processing.

ini_gets() * \param Section the name of the section to search for * \param Key the name of the entry to find the value of * \param DefV

Detect RP2350 from section addresses.
