Prettier Configuration File for uniform js formatting

[vorburger]

I want to propose some changes to the gulpfile.js for #23 but by VSC considerable reformats that file every time I touch it.

This is because I have the Prettier Code Formatter VSC Extension installed.

Would this project's maintainers welcome a PR which contribs an appropriate Prettier Configuration File to settle on a uniform JS format for this project?
