feat: support pseudo selectors escape

Support pseudo selectors escape

This pull request adds support for escaping pseudo selectors, for example:

• .btn\:hover is a a class with no psuedo selector applied <div class="btn:hover">
• .btn\\:hover is a class with a psuedo selector applied <div class="btn\">

Motivation:

In tailwindcss it's common to use classes containing : such as: <div class="group-hover:peer-checked:hover:opacity-100">. At the moment these escaped classes lead to errors such as:

DOMException: Failed to execute 'insertRule' on 'CSSStyleSheet': Failed to parse the rule '.peer:placeholder-shown:focus ~ .peer-placeholder-shown\:peer-focus\:left-3, .peer:placeholder-shown.pseudo-focus ~ .peer-placeholder-shown\:peer-focus\:left-3, .pseudo-focus .peer:placeholder-show ~ .peer-placeholder-shown\:peer-focus\:left-3 { left: 0.75rem; }'.

As well as unwanted behaviour, the class mentioned above with corresponding styles:

.group:hover .peer:checked ~ .group-hover\:peer-checked\:hover\:opacity-100:hover {
  opacity: 1;
}

is being rewritten incorrectly causing, conditional styles to not be applied. Here is a comparison of resulting classes before and after pull request:

- .group.pseudo-hover .peer:checked ~ .group-hover\:peer-checked\.pseudo-hover\:opacity-100.pseudo-hover
+ .group.pseudo-hover .peer:checked ~ .group-hover\:peer-checked\:hover\:opacity-100.pseudo-hover
