ENH: Add Multivariate Hypergeometric Distribution

See original GitHub issue

Part of “A Solid Foundation for Statistics in Python with SciPy”.

Add Multivariate Hypergeometric Distribution to scipy.stats.

Be sure to follow the guide Adding a New Statistics Distribution carefully and see gh-6375 for an example of adding a related distribution. See methods inherited from multi_rv_generic in _multivariate.py, although I guess there’s not too much and most of it needs to be implemented from scratch.

No, you don’t need to add the C++ code. Please just implement the marginals methods as @WarrenWeckesser suggested, and if it is too slow, we can look at replacing it later.

BTW @tirthasheshpatel while I’d suggest following @WarrenWeckesser’s suggestion, don’t worry about speed too much here. If it is not fast enough, we have permission to add these random number generators under the BSD license, and we’ll already be laying the groundwork for the noncentral hypergeometric distributions. It would be easy to also add the multinomial random number generator.
