WIP: Add tailwind-jit transformation

[regisphilibert]

This PR, not ready for promotion, (but maybe use?) is here if we need it.

This will essentially use the current best workaround to run Hugo Pipe + JIT described by @Gioni06 here: https://dev.to/jonas_duri/how-to-use-tailwindcss-30-without-external-npm-scripts-just-hugo-pipes-2lg9

Requires Node 16

# _huge/config/styles.yaml
styles:
- name: main
  path: css/main.scss
  use:
    - tailwind-jit

The stdin error (reported as fixed in Tailwind 3.0.11) is still there for me. So it means a I had to add a stdin empty file at be root of the repo to have this work. Less than ideal.
