file-type-ts

The credit for this is due to Sindre Sorhus and his great project: file-type

This is forked from version 17.1.1 of his library. All I've done is trim out a few things that I didn't need and convert it to TypeScript.

THIS TYPESCRIPT ADAPTATION FROM SINDE'S WORK HAS NOT BEEN THOROUGHLY TESTED. It's a proof of concept.
