arrayglyph/replace array by masked array

[MAfarrag]

Internal improvement

• replace the normal numpy array in the constructor method by masked array in order not to convert all input arrays to float32.
• Now all the arrays will stay the same type as they have ben given, so if the array is int the mask (np.nan) will be stored in the array without converting it to float.
• Now we don't need to use the prepare_array method to scale the values if they are already between 0-255 which matplotlib already understand.
• the percentile/surface_reflectance parameters to the constructor method are None by default, so no processing is done to the given array except when the previous parameters are given.
