  1. fix: avoid cancellation in stats/base/dists/kumaraswamy/logcdf 

    `ln( 1 - (1 - x^a)^b )` cancels twice: `1 - x^a` rounds away the
low-order bits of a small `x^a`, and `1 - (1 - x^a)^b` loses the digits
of a small CDF, as `ln` of a value close to `1` does for a CDF close to
`1`. Evaluate `ln(1-x^a)` with `log1p` or `expm1`, depending on the
size of `x^a`, and finish with `log1mexp`. Add fixtures generated from
the textbook formula in extended precision.
