Chatterjee coefficient

[kahaaga]

Implements the feature requested in #379.

Changes related to feature

• Incremented minor version to 4.1.
• Added changelog entry.
• Implemented ChatterjeeCorrelation association measure.
• Implemented SurrogateAssociationTest dispatch for the measure, which shuffles the first variable.
• Added documentation entry. The docs are here.
• Added reference to the measure in the association measure/estimator tables.
• Examples: Example 1: computing the Chatterjee coefficient for independent/dependent variables. Example 2: using a SurrogateAssociationTest to test the significance of association.
• Tests: comparison to the original authors R-package implementation (in the case of no ties). For the tied case, we can't compare directly, because the R-package doesn't have an y way of controlling the randomisation step. I also verify correctness by testing p-values with a SurrogateAssociationTest.

Other changes

• Updated changeling with new package name and version.
• Updated badges in readme.md.
