Publish New NPM version for Node-Static

Hey 👋 I notice its been a while since a new version of node-static has been pushed to NPM, and the version that currently exists there contains the package [minimist](https://www.npmjs.com/package/minimist) which has a ([github advisory](https://github.com/advisories/GHSA-vh95-rmgr-6w4m)) for it. This package was being used which is used by a package in this project called [optimist](https://www.npmjs.com/package/optimist). In [this pull request](https://github.com/cloudhead/node-static/pull/227/files#diff-7ae45ad102eab3b6d7e7896acd08c427a9b25b346470d7bc6507b6481575d519L29), @brettz9 removed optimist to resolve this vulnerability. As a result, publishing a new version of `node-static` will ensure that all users of this package will use a safe version by default.
