iio:event: Add timeout event info type
For adaptive threshold events, the current value is compared with a
(typically) low pass filtered version of the same signal that slowly
tracks large scale changes. However, sometimes a step change can
result in a large lag before the low pass filtered version begins
to track the signal again. Timeouts can be used to made an
instantaneous 'correction'. Documentation of this attribute
is added in a later patch.
