Digital IO library

The Digital IO Library is used to read or write a digital signal from a n number of channels based on different modes and a pulse width.

The available modes are : - NONE - HIGH - LOW - TOGGLE - PULSE

The library defined an interface which allow to easily extends to different types of IO device.

Advantech IO

Implementation present in past version of Falcon but removed because it needs a separate/private set of libraries. It can be re-implemented in a separate extension if needed in the future.
