Alignment, consolidation, and error updates

[rboiteau]

Updates:

• Alignment function 'run' now uses concatenated Pandas dataframe for faster alignment. Previous function is now 'run legacy', which can be used by setting 'coremstools.parameter.alignment_legacy' to true.
• Consolidation function now has 'min_samples' parameter, that specifies the minimum value in 'N Samples' for a primary candidate of a consolidated group.
• Consolidation_width moved to 'coremstools.parameters.consolidation_width'
• Added function 'load_feature_list'
