Support custom tailwind prefix

[UnknownPlatypus]

For projects that have class names that conflict with Tailwind CSS utilities, you can prefix all Tailwind-generated classes and CSS variables using the prefix option.

It seem currently rustywind ignores these, so it does not sort most of the classes. Would it be difficult to support this ?

Below some details about the syntaxes for v3 and v4 ⬇️

---

Tailwind v3

Tailwind v3 prefix docs

<div class="tw-text-lg md:tw-text-xl tw-bg-red-500 hover:tw-bg-blue-500">
  <!-- -->
</div>

Tailwind v4

Tailwind v4 prefix docs

<div class="tw:text-lg tw:md:text-xl tw:bg-red-500 tw:hover:bg-blue-500">
  <!-- -->
</div>

The main difference between v3 prefixes and v4 prefixes is that in v3, the prefix was part of the utility where as in v4 it is _always in front of the CSS class.

So, for example, this in v3:

hover:-tw-mr-4
tw-text-lg

Would be converted to the following in v4:

tw:hover:-mr-4
tw:text-lg
