Crate iter_opt_filter

This library adds the optional_filter which is provided for all Iterators by the IteratorOptionalFilterExt extension trait.

The optional_filter takes an Option<fn(&item) -> bool>, which allows for easy conditional filtering. This however comes at a performance cost compared to a normal filter or the inner Iterator by itself. But it is generally faster than a Box<dyn Iterator>.

See examples on the optional_filter method.
