Re-implement nuclinfo using `AnalysisBase` style subclasses

[ALescoulie]

Is your feature request related to a problem?

To complete the overhaul of nucinfo we need to rebuild the rest of the functions in the analysis base style in the nucleicacids module.

Describe the solution you'd like

Using the NucPairDist as a super class rebuild

dists = MinorPairDist([ag1, ag2],[ag3,ag4], U)
dists.run()

TODO

• rebuild minor_pair
• rebuild major_pair
• rebuild phase_cp
• rebuild phase_as
• rebuild tors

Additional context

In the last update in PR #3611 the I began the process of overhauling nuclinfo, and I would like to finish that process.

[ALescoulie]

I'm starting on this and hopefully can get a PR out soon.

[ALescoulie]

I just pushed PR #3735 which add major and minor pair, I'm also working on the torsion angle class, which is a little more involved.

See #3744 for a discussion on how to represent the typical output data in the Results dict.

Re-open because PR #3735 did not update all classes.
