Add ComplexityMeasures.jl interface support

Describe the feature you'd like to have

Recently in RecurrenceMicrostatesAnalysis we have added full support for the ComplexityMeasures.jl API; this came with a lot advantages, in particular (1) formalizing obtaining and analyzing the probabilities corresponding to various microstates, and (2) making it clear and explicity how all the various recurrence microstate analysis metrics are complexity measures.

We should do the same here! We have methods that return histograms for diagonal or vertical lines, and this is what an extension of the probabilitiesAPI can provide.

Cite scientific papers related to the feature/algorithm

To my knowledge there aren't any papers that present RQA as complexity measures in the way of ComplexityMeasures.jl as functionals of probability mass functions or not.

If possible, sketch out an implementation strategy

Thankfully that's very easy, follow the tutorial of RecurrenceMicrostatesAnalysis.jl: https://juliadynamics.github.io/DynamicalSystemsDocs.jl/recurrencemicrostatesanalysis/stable/

The old RQA API will all stay exactly as is of course and still be available as the RQA community is very large and don't have to relate RQA with complexity measures.

Start with the RecurrenceMicrostatesAnalysis.jl tutorial linked in the issue, then inspect the existing diagonal- and vertical-line histogram methods in RecurrenceAnalysis.jl. The work is done when a ComplexityMeasures.jl-compatible probabilities interface is available while the existing RQA API remains unchanged.
