def multiband[K, V](rdd: RDD[(K, V)], alpha: Double, beta: Double)(implicit arg0: (V) ⇒ MultibandTile): RDD[(K, MultibandTile)]

Given an RDD of MultibandTile objects and parameters alpha and beta, return an RDD of tiles where the sigmoidal contrast operation has been performed on each band of each tile.
Given an RDD of MultibandTile objects and parameters alpha and beta, return an RDD of tiles where the sigmoidal contrast operation has been performed on each band of each tile.
The approach used is described here: https://www.imagemagick.org/Usage/color_mods/#sigmoidal
rdd
An RDD of input tiles
alpha
The center around-which the stretch is performed (given as a fraction)
beta
The standard deviation in the computation, used to avoid saturating the upper and lower parts of the gamut
returns
An RDD of output tiles
