[Feature Request] Polylogarithm

3

Dear SpecialFunctions community, I would like to request a feature: [the polylogarithm](https://en.wikipedia.org/wiki/Polylogarithm).

Hey, I end up needing the Debye function D_1 from https://www.gnu.org/software/gsl/doc/html/specfunc.html#debye-functions Would be nice to have this type agnostic and not Float64-only-because-C++

beta_inc in the degenerate cases

4

So we allow one (but not both) of the parameters in `beta_inc` to be zero https://github.com/JuliaMath/SpecialFunctions.jl/blob/d829f0ac1ebab6d339bf8bada710bde50735ee7d/src/beta_inc.jl#L741-L742 but in that case the integrated density degenerate. In the original version from the...

Test type-stability of functions

10

Use `@inferred` to test type-stability of functions. * `besselj` and `bessely` are unstable in Julia 0.6 and 0.7. * `digamma`, `trigamma`, `invdigamma`, `polygamma`, `eta`, `zeta` are unstable in Julia 0.7...

Added faddeeva_w function

16

"w", the mother of all Faddeva functions, can be useful. This function is named wofz in python/scipy (Cf. http://ab-initio.mit.edu/wiki/index.php/Faddeeva_Package). It is called faddeeva_w in this PR.
