Make protected Stream::parseInt/Float overloads public.

Stream::parseInt & Stream::parseFloat previously had protected
overloads which allowed skipping a custom character. This commit
brings this feature to the public interface.

To keep the public API simpler, the single paramter overload remains
protected. However its functionality is available in the public
interface using the two parameter overload.
