Vulnerability in optimist: consider replacing #28
Description
I'm getting a dependabot alert for minimist < 0.2.1: CVE-2020-7598.
Currently, ejs-cli depends on optimist 0.6.1, which depends on minimist 0.0.10.
Optimist appears to have been abandoned, and has a deprecation notice directing users to yargs or nomnom.
You may want to consider replacing optimist with yargs. While it's not a trivial change, it doesn't look too complex — I made an attempt on a fork of this repository, but ejs-cli has stopped working in my project, so I can't test it properly.
