feat: allow to pass pug locals with <pug> tag using custom attribute

[felixranesberger]

I have the problem that I need to pass a file specific modifier class to the tag. This pull reqest allows to pass pug locals to individual pug tags via encodeURIComponent strings.

I would appreciate feedback on the implementation, as I'm not sure if there is a better way.

HTML Code

<pug src="assets/templates/source/04-elements/forms/button.pug" locals="%7B%22modifierClass%22%3A%22btn%20btn--neutral%20btn--wide-max%22%7D" />

Pug File:

button(class=modifierClass) Hello World

Hi, any feedback on this pull request? :)

I think this feature is a good idea as it would make templates more reusable, even if the proposed syntax isn't exactly eye candy. However, the change doesn't pass the tests.
