wlcutter: Set intensities of a given bandpass to a preset value...
In CMET-UGent/MicroRaman: Phenotyping of microbial Raman spectroscopy data

This function converts takes a list of MALDIquant::massSpectrum objects and sets the intensitiy values between certain wavelengths to a given value. By default, this value is zero, as this function can be used to remove errant peaks from the spectra.

1	wlcutter(x, lower_wl = 900L, upper_wl = 1100L, new_intens = 0L)

`x`	a list of MALDIquant::massSpectrum objects
`lower_wl`	an integer of the lower boundary of wavelenghts to replace intensities for (defaults to 900)
`upper_wl`	an integer of the upper boundary of wavelengths to replace intensities for (defaults to 1100)
`new_intens`	new intensity value to assign to all peaks between lower_wl and upper_wl. Defaults to 0. Needs to be a single integer value (for now).
