Clarify chain_ll() documentation

[jamesmbaazam]

This PR seeks to clarify the documentation of chain_ll() so that it states that the function is used to estimate log-likelihoods, not likelihoods. All occurrences of "likelihood" have been replaced with "log-likelihood" in the documentation.

This PR closes #73.

Looks good to me - thanks!

All the changes look good.

A note for future PRs, if you feature branch is behind main (as was the case for this PR) it is better to rebase the feature branch onto the head of main. This provides a cleaner commit history by removing the merge commit.

True although as a counterargument they require a force push (and sometimes resolving conflicts across multiple commits) which can be more involved / harder to track down problems.

I agree that both methods have their advantages & disadvantages. I'm just parroting the Epiverse protocol explained in blueprints.
