feat: Add Pareto Distribution

[LidiaDomingos]

Description of Change

This feature proposes implementing the Pareto distribution to generate random numbers or model data in circumstances where the 80/20 rule applies (https://en.wikipedia.org/wiki/Pareto_distribution). When modeling phenomena with a heavy tail, including wealth distribution, natural phenomena, or other skewed distributions where a few number of occurrences account for the majority of the effect, the distribution is especially helpful. The feature should offer capabilities for sampling from the distribution and let users set the shape parameter (α) and scale (xm) parameter.

Checklist

• Added description of change
• Added file name matches File name guidelines
• Added tests and example, test must pass
• Added documentation so that the program is self-explanatory and educational - Doxygen guidelines

Notes: I think the Pareto distribution is important because it is used in various disciplines, including economics, finance, and environmental research. In my instance, I used for modeling data where a small subset of the population has a significant impact, such as income distribution or asset allocation.
