I.e. for a specified time, they count the number of conditions that have occurred, and then signal if that is more than a specified amount. `IIO_EV_INFO_PERIOD` resets when the condition no longer is true and is therefore not suitable for these devices. Add a new `iio_event_info` `IIO_EV_INFO_RUNNING_PERIOD` that can be used as a running period. Also add a new `IIO_EV_INFO_RUNNING_COUNT` that can be used to specify the number of conditions that must occur during this running period.
