feat: highlighting functionality

[infi-pc]

Problem

I would like to generalize Productboard's use-case that highlights all components based on some criteria (usually CSS selector)

Solution

I think we could take this as a base: https://github.com/infi-pc/locatorjs/compare/master...productboard:locatorjs:master

I would add

• query param support - when we get CSS selector in query param, it automatically highlights the components
• UI support - when I input the CSS selector to the input field, it highlights the matching component on the go.
