Add random walks to rustworkx

[nahumsa]

What is the expected enhancement?

Add functions that make a random walk on a graph, which could be both a biased or an unbiased random walk. This may be important for some network science applications.

In my opinion, this would be done by two functions:

• random_walk for the unbiased random walk;
• biased_random_walk for the biased random walk.

Hey, I'd love to help out with this!

Hi, @areeq-hasan! You can choose any of those two types of random walks to implement. I started implementing the unbiased random walk and got stuck with the WalkingNeighbors part of the implementation, I think that it would be better to have a custom implementation for the walker. However, I got busy with other things and was not able to create that custom implementation. I plan on getting back when I have more free time, but fell free to try to solve it our way. :) Feel free to ask if you have any questions.

Great, I'll give a custom walker implementation a shot!
