* a conversion function like `std::stod`, accepting a `std::string` and a
* `size_t*`. The argument `type` is only used to generate proper error
* messages and should be the string representation of `T`. If `T` is
* unsigned, checks that `optionarg` contains no minus. Then `conv` is called
* and the error conditions are handled: `conv` may throw an exception or
* `pos` may be smaller than the size of `optionarg`, indicating that not the
* entirety of `optionarg` was parsed.
