[FEAT] Parameter generators

[hsloot]

Summary

At the moment, the package does not provide any functions to generate Marshall--Olkin parameter. for high dimensional models.

Proposal

Provide helper functions to generate various types of Marshall-Olkin distribution parameters. These could first be used internally to improve and extend testing.

[hsloot]

The implementation for test purposes should be simple, but extensive. Furthermore, it should be possible to feed all possible models such that profiling becomes easier.
