Rcs - Range of cumulative sum (R_c**s)

R_c**s is the range of a cumulative sum (Ellaway 1978) of each light-curve and is defined as:

$$R_{cs} = max(S) - min(S) \\\ S = \frac{1}{N \sigma} \sum_{i=1}^l (m_i - \bar{m})$$

where max(min) is the maximum (minimum) value of S and l = 1, 2, …, N.

R_c**s should take a value close to zero for any symmetric distribution:

>>> fs = feets.FeatureSpace(only=['Rcs'])
>>> features, values = fs.extract(**lc_normal)
>>> dict(zip(features, values))
{'Rcs': 0.0094459606901065168}
