Avoid duplication with / Reuse code from eaf package?

[MLopez-Ibanez]

The eaf package: https://github.com/MLopez-Ibanez/eaf
provides a more recent implementation of the hypervolume C code and it also provides functions for weighted hypervolume, epsilon, igd, igd+, and Averaged Hausdorff Distance: https://mlopez-ibanez.github.io/eaf/reference/index.html#multi-objective-performance-assessment-metrics

In addition, it provides quite fast implementations of dominance checks and filtering, normalisation, pareto ranking (nlogn for 2D), etc.

Of course, if there is anything you don't like or you think can be improved, suggestions and comments are welcome.

This package is in maintenance mode. Maybe I should spin a release that points people toward the eaf package?

[MLopez-Ibanez]

An update for people who may find this issue in the future. The eaf package has been completely superseded by the moocore package: https://multi-objective.github.io/moocore/r/index.html
