Support latest JavaScript and TypeScript, overhaul cli opts, etc.

Finally got around to using this library again, and got everything
updated.

* Use espree instead of esprima
* Update to latest deps
* Use more standard cli opts
* Switch to ESlint for linting
* Remove old config files and unused packages
