dep(parse-url): replace with native URL

[msimerson]

• Fixes #37
• replace Travis CI with GitHub Actions
  • add codeql
  • add windows testing (can be ignored or easily disabled)
• CI with GitHub Actions has been tested and you can see the output over here in my fork and in the screenshot below. I updated the readme file so that if you merge this PR, the CI test badge points to the GHA tests in your repo.
• the CI tests against v8 and automatically against every LTS version of node.js. Currently that's node 18 & 20. If dropping node 8 support is acceptable, then the polyfill can be removed.
• After merging this PR, coveralls will show results in your fork.
• This PR is minimal, changing only what is required to remove parse-url and get GHA testing functional
