Augmentation Methods

AddNoise	Add noise to input data from various probability distributions.
BaselineShift	Adds a constant baseline to the data.
FractionalShift	Shift signals by a random fractional amount using cubic spline interpolation.
GaussianBroadening	Transform spectral data by broadening peaks using Gaussian convolution.
IndexShift	Shift the spectrum a given number of indices between -shift and +shift drawn from a discrete uniform distribution.
SpectrumScale	Scales the data by a value drawn from the uniform distribution centered around 1.0.
