Getting purgecss to read from stdin

The purgecss CLI does not (currently) read css from stdin. Here is a short node script to make that happen.

The command line looks like:

purgecss_stdin <output file>

If no output file is given, it writes to stdout.

It will automatically read a purgecss.config.js file if it is available.

A usage example:

npx tailwind build src/css/styles.css | purgecss_stdin build/dist/styles.css
