[Feature Request] Dunnett's test about fsharp.stats HOT 3 OPEN

Dunnetts q distribution is necessary for implementation. Since this is not trivial it may be sufficient to cover distinct alpha levels and use q-value tables for analysis, instead of implementing the distribution

• Suggestion: alpha levels 0.05 and 0.01

Dunnetts test was implemented with unit tests and documentation. A table for two sided tests with a significance threshold of 0.05 is provided and should be extended for a higher sample count and various significance thresholds.
