Consider using np.random.default_rng for self-contained randomness

[micimize]

Setting np.random.seed is alright, but IMO it would be better to add a seed + RNG to each generator using np.random.default_rng(seed) so that their RNG is self contained.

This is because a lot of other code mazelib gets integrated with may make use of the "global" rng, making reproducibility more challenging for depending projects.

That seem like a cool idea, sure.

I should probably read the docs there and play with the two, just to make sure. But from your description, I agree that would be a useful improvement.

I'm for it.
