Expand the summaries module in ltu-cmass to include all ili-summarizer methods

[maho3]

Currently, ltu-cmass only supports generating its own internal survey P(k) in cmass.summaries.Pk_nbkit. However, it would be useful if we could easily flag a configuration file to produce all the other summaries in ili-summarizer.

This would require redoing the cmass.summaries module so that it is purely a wrapper for ili-summarizer. However, we would like it to maintain the hydra configuration style of other pipeline steps.

Definition of done

• [ ] Add ili-summarizer as an ltu-cmass dependency
• [ ] Replace the cmass.summaries.Pk_nbkit with one which uses ili-summarizer's Pk
• [ ] Add other ili-summarizer summaries as sub-modules of cmass.summaries, or within one big 'SummaryRunner' configuration
• [ ] Update VPF and CiC summaries to use kdtrees for speed; test with cmass data formats
