Feature request: for multiplicative scatter correction

[Ayoubzinini]

Hello developpers team, Thank you for your good work on this package Would you please add the multiplicative scatter correction to the signal correction functions? This is an example using python

I think this is a very niche utility that is not available as a standard DSP function. JDSP is a library which provides standard functions and can be used to build such functions (as MSC) easily.
