Improvement rng 50
The algorithms for small mean and large mean have been separated into
dedicated classes. Caching of constants used in the algorithm has been
used to increase speed.
Note: I have run `mvn clean verify` within the `commons-rng-sampling`
module but the randomness of the `ContinuousSamplerParametricTest` causes it to
fail on different distributions. I have seen failures on:
- Box-Muller Gaussian deviate
- org.apache.commons.math3.distribution.LevyDistribution (inverse method)
These are unrelated to the PoissonSampler.
I ran `mvn clean verify -DskipTests=true` and that had no errors.
No checkstyle errors in the project files modified in this PR.
