@brief Create a new gpiochip iterator.
@return Pointer to a new chip iterator object or NULL if an error occurred.
Internally this routine scans the /dev/ directory for GPIO chip device
files, opens them and stores their the handles until ::gpiod_chip_iter_free
or ::gpiod_chip_iter_free_noclose is called.
