NOTE: this module will be renamed `pw_digital_io` immediately in a
follow-up change.
The Digital IO interface represents individual GPIO lines that support
some combination of input, output, and/or interrupt functionality.
The choice of supported capability, and most other configuration details
are left up to the backend implementation.
