IteratorExt -like trait to put FilterKeyValue capabilities onto Iterator<Item=Token>

[Byron]

The last time I tried, this didn't work for me as I couldn't figure out the right syntax for some reason. Maybe stackoverflow can help ?

This would allow something like:

println!("{}", Lexer::new(r#"{"v":null}"#.bytes(), BufferType::Span)
                               .filter_key_value_by_type(TokenType::Null)
                               .reader()
                               .collect::<String>())
// prints "{}"
