[FEATURE] Command line version of SpectralAnalysis

[AlanRace]

Develop a command line (compiled) version of SpectralAnalysis. This could be either a monolithic tool where the commands specify which feature is desired, or individual tools for each feature.

Features include:

• Open data (open dataset in DataViewer; must specify data location and parser if multiple possibilities for same file extension)
• Perform preprocessing and save (must specify data location and parser, and preprocessing workflow file)
• Perform multivariate analysis/machine learning (must specify data location and technique to use)
