[Feature] Pack Comparison Page

[3vorp]

Is your feature request related to a problem?

It's hard to explain to users the differences between each pack, and it's been long requested to have a proper comparison page.

Describe the feature you'd like

Two separate but related features:

• Add a pack comparison page which lets you choose from a range of images and compare any two packs arbitrarily with a slider (see screenshot).
• On the pack page, have a "reference" field in the yaml files where that pack's screenshots will be used as the comparison slider, without the extra customizability (this allows progart to reference progart and 64x to reference 32x).

Screenshot(s)

Notes

Useful components/libraries that may come in handy:

• https://vuetifyjs.com/en/components/carousels/#usage
• https://www.npmjs.com/package/@img-comparison-slider/vue

Now that Faithful has moved to a unified download page, it might be a good idea to just add a comparison section to the downloads page directly instead of putting it on the pack pages (there should still be a more general screenshot section + links to the comparisons on the pack pages though)
