Exponential smoothing.
This implements an exponential moving average smoothing of parameter alpha (https://en.wikipedia.org/wiki/Exponential_smoothing) such as (s being the filtered values and x the raw data):
Nodata values are excluded from the moving average calculation. It takes the following arguments:
The standard behavior for this filter is obtained by using a left window. If using a right window, it behaves as if time was reversed (ie. predictions from the future). A centered window applies the standard algorithms on the distance between the center point and each points, that is that points get averaged symetrically around the middle point before running the standard algorithm.

| A function that computes the start and end for a window for the 'index' element from ivec The principle is to compute the first index that matches the minimum number of points criteria, and the one that matches the minimum time window, then combine them (with the equivalent of OR: we take the MIN index). Afterward, we compute the last index [...] for number of points and the last index [...] for the time window and combine them (with the equivalent of OR: we take the MIN index) or vice versa for right centering.
