no method matching _erf(::Complex{BigFloat})

Hi,

This package is great, BigFloat and Complex are supported for erf and erfc, and the implementation is fast.
However, the combination of BigFloat and Complex is not supported. It would be great to add support for it, example:
erf(big(1.1im))

ERROR: MethodError: no method matching _erf(::Complex{BigFloat})
Closest candidates are:
_erf(::Float64) at ~/.julia/packages/SpecialFunctions/9pXme/src/erf.jl:15

Yes, this is not currently implemented. It’s not trivial to extend special-function algorithms to support arbitrary precision, unfortunately.
