Loggaby v3.0.0

• (Breaking Change) Transports will now receive an array of arguments instead of a single string, which can either just be .join()'d or formatted (TerminalTransport does this)

So users can now use formatting like the standard console.log:

const Loggaby = require('loggaby');
const logger = new Loggaby();

logger.log('Hello %s!', 'World');
