Consider making BIO and SSL pure representations of their underlying objects

[The-Voidwalker]

Currently both BIO and SSL are setup in a way that only supports my specific use cases. It could make some sense to open them up considerably so they function similarly to a wrapper for the interop functions. This would necessitate changing how the constructors work so they don't do any setup on their own, and moving that logic somewhere else (probably a helper class in the Client folder?).

This is a distant TODO though, as technically it isn't necessary for getting the WebClient itself working.
