introducing the sequel to #240

this does some assorted optimizations to cellularnoise, dbpnoise, and worleynoise, as the title suggests:

  • replacing write! with string.push()
  • using String::with_capacity / Vec::with_capacity where possible
  • instances of rng.random_range(0..100) are replaced with using rand::distr::Bernoulli
