  1. Keep the binomial upper tail precise instead of rounding it to zero [… 

    …patch]

BinomialDistributionProvider fell back to IDistribution's 1 - Cdf for its
survival function, so any upper tail below about 1e-16 came back as zero.
Evaluate it directly as I(p; k + 1, n - k), as Poisson already does with
its own complementary incomplete function.

Fixes #50

  2. Keep the geometric CDF and quantile precise for a rare success [patch] 

    GeometricDistributionProvider worked with 1 - p directly, which rounds to
exactly one below p of about 1e-16: the CDF was zero everywhere and the
quantile's correction loop walked to int.MaxValue, about 22 s per call.
Store log1p(-p) and build the CDF, survival function, mass and quantile on
it through the shared ExpM1/Log1P, and bound the quantile's correction walk
to two steps either way before falling back to bisecting the support.

Fixes #51
