Replace metaparser library

[marcovtwout]

npm audit reports a vulnerability in a dependency of the metaparser library:

  High            Denial of Service
  Package         css-what
  Patched in      >=5.0.1
  Dependency of   cli-real-favicon [dev]
  Path            cli-real-favicon > rfg-api > metaparser > cheerio >
                  css-select > css-what
  More info       https://npmjs.com/advisories/1754

The latest release of metaparser uses the latest release of cheerio (v0.22), which uses an outdated version of css-select, which uses the vulnerable version of css-what. I don't think this issue has much impact, but it would be good to fix it nonetheless.

The metaparser package has its latest release 6 years ago and unfortunately the link to source returns a 404:

• https://www.npmjs.com/package/metaparser
• https://github.com/haydenbleasel/metaparser

Perhaps the best course of action is to find an alternative for metaparser and replace it?
