All random generation should be settable with numpy random generator

[paucodeici]

I am not aware of where exactly there are call to numpy.random but it should be call to some random number generator fed in the function.

Typically pointpats.random.poisson( rng=np.random.default_rng(???)) or specify a seed or something

Can do the change but I am not aware if it would break anything or would be long and painful change.

Fully agree. Right now we call individual functions from numpy.random inside our functions like here

pointpats/pointpats/random.py

Line 240 in 8c20108

candidate = numpy.random.multivariate_normal((0, 0), replication_cor)

or here

pointpats/pointpats/random.py

Lines 150 to 151 in 8c20108

	numpy.random.uniform(bbox[0], bbox[2]),
	numpy.random.uniform(bbox[1], bbox[3]),

If you want to fix the random seed, you need to use the global numpy.random.seed. We should transition towards random generator support. The change should not be too complicated. We just need to expose rng and use methods on rng to draw random samples instead of current functions.
