Support for the script option for pageres-cli

[honzajavorek]

Hi, I'm happy with using pageres-cli for most of the screenshots I need, but for a small fraction I'd like to add a script to scrape the screen properly. The pageres library has the script option, but pageres-cli doesn't (or at least it isn't documented). I'd be willing to work on a PR to add this option. Would you accept such change?

My idea would be only to support loading the script from a file, I don't think supporting JS passed in a string is very convenient for a CLI.

I think I just forgot to add it to the CLI.

For now, you could use https://github.com/sindresorhus/capture-website-cli instead, which does have such a flag.

This flag should work the same as in capture-website-cli.

Oh, nice. What is the main difference between capture-website-cli and pageres-cli? The READMEs link each other, but only with words that it's a different take, which doesn't explain much whether it uses a different technology, improves CLI, or one deprecates the other for some reason.
