Add Danbooru::Archive library for handling .zip and .rar files.

Introduce a new Danbooru::Archive library. This is a wrapper around libarchive that lets us extract
.zip, .rar, .7z, and other archive formats. Replace the rubyzip library in MediaFile::Ugoira with
the new Danbooru::Archive library.

This is a step towards fixing #5340: Add support for extracting archive attachments from certain sources.

This adds a new dependency on libarchive. Downstream users should `apt-get install libarchive13` if
they're not using Docker.
