Mindstorm: Advanced neuroimaging analysis

This version adds functionality for running general linear models using Nilearn.

• Utilities for creating GLM design matrices have been added in the new glm module.
• Scripts for estimating betaseries models using the least squares–separate (LSS) approach have been added. There is a script, betaseries-bids, for running LSS models on BIDS-compliant data preprocessed using fMRIPrep, and another script, betaseries, for fitting to generic timeseries data.
