feat: add support for mj-html-attributes, mj-selector, and mj-html-attribtue

[codedninja]

Do to the limitation of not wanting to parse the whole rendered HTML, this feature doesn't support CSS child combiner syntax. It only supports current element syntax. Examples of query selectors are listed below.

I do think there is a better way to inject the HTML attributes when calling Tag::render_open() or Tag::render_close() in packages/mrml-core/src/prelude/render/tags.rs. Though I am still learning Rust, I couldn't think of a good way to do so yet.

a[href]
.super_duper_class
#id_tags
div[parm="true"]
