Add eficient hypergeometric

[aloctavodia]

This adds hypergeometric distribution. Both the cdf and ppf are computed numerically. The ppf is off by one, not sure why as all other tests are passing. In the meantime, I am handling the hypergeometric as a special case.

This also updates the find_ppf function to make it work with discrete distributions.
