list features to be moved from alchemical-analysis to alchemlyb

[orbeckst]

We would like to produce a list of highly desirable alchemical-analysis features in alchemlyb.

As expressed in the Roadmap, the idea is to use little pieces from alchemical-analysis and re-implement in alchemlyb together with tests and docs.

@alchemistry/alchemlyb : Please add what you want to see (or what you want to contribute) to the wiki page alchemical analysis features.

Once we have a list of features that we agree to be important then it becomes a bit easier to spend resources on working on them.

Added my comments. I think this pretty much covers it; @brycestx and @shuail , anything else from your end?

Looks good to me. Thanks for drafting this up!
