Natural logarithm of the absolute value of the beta function, log|B(a, b)|.
Equivalent to R's lbeta(). Takes single numbers.
For a, b > 0 with the larger argument above 15, it is computed as
lgamma(small) - [lgamma(large + small) - lgamma(large)] with the bracketed difference
evaluated without cancellation, so accuracy is kept for large arguments.
