Replace Pica library for resizing images

[corbindavenport]

PhotoStack currently uses the Pica library for resizing images. We're stuck on version 7.0, because version 7.1 and later throw this error in Firefox (and possibly other browsers):

Uncaught (in promise) Error: Pica: cannot use getImageData on canvas, make sure fingerprinting protection isn't enabled
    resize https://cdn.jsdelivr.net/npm/pica@7.1.0/dist/pica.min.js:13
    promise callback*["/index.js"]</v.prototype.resize https://cdn.jsdelivr.net/npm/pica@7.1.0/dist/pica.min.js:13

This will not be fixed in Pica, so the library needs to eventually be replaced with a different one or a native browser function.

I just added a comment on Pica's repo: nodeca/pica#244 (comment)

TLDR: You don't need to wait for a new pica release (or even a new PhotoStack release for that matter), you can apply some fixes yourself using something like patch-package.
