Initial implementation of Blue Noise Sampling, as described in https://dl.acm.org/doi/10.1145/3306307.3328191.
Fixes #166
Note: this is not a 100% full implementation yet - even when using the
--sampler blue, some decisions are made based on arng.gen()random sampler. Fully deterministic use of the sampler should be completed in later PRs.Check the full-resolution images at 100% zoom level. Left: random sampling. Right: blue noise sampling.
