Opposite of .has() about visdom HOT 4 CLOSED

Sorry, there's no method opposite to thehas() method yet. Currently you may need do such thing like below:

let html = r#"
    <div><p></p></div>
    <div></div>
    <div></div>
"#;
let root = Vis::load(html)?;
let divs = root.find("div");
let divs_has_p = divs.has("p");
let divs_not_has_p = divs.not_in(&div_has_p);

I think i should add the :has pseudo selector, so you can do this by a simpler way:

let div_not_has_p = divs.not(":has(p)");

I will add that later, thx for your feedback.

@rrjanbiah The :has pseudo selector has been added in the new version 0.5.2, examples can be seen in the test case function test_selector_pseudo_has https://github.com/fefit/visdom/blob/main/tests/selector.rs#L829. Thx again for your feedback :)
