index.js: Fallback to require(...) for unrecognized reporters

This allows us to use reporters that aren't built in. For example, with this commit you can: $ npm install $ npm install --no-save mocha mochawesome $ cp index.js node_modules/tap-mocha-reporter/ $ cp lib/*.js node_modules/tap-mocha-reporter/lib/ $ npm test -- --reporter=mochawesome That's installing [email protected] and [email protected].
