Internal function (used by s2_mask) which smooths and buffers a 0-1 mask image in order to reduce the roughness of the mask obtained from SCL classification (which is done pixel by pixel). See details.
smooth_mask(inmask, binpaths, tmpdir = tempdir(), radius = 250, buffer = 250, namask = NULL)
The path of the input 0-1 mask (where 0 represents the area to be masked, 1 the cleen surface).

(optional) The path of an input 0-1 mask where 0 represents the area of the original file with NA values (which should not be smoothed / buffered). Default (NULL) means that no NA values are presente.
The path of the smoothed mask.
