Handle many files as a zip archive (#1688)

* Handle many files as a zip archive

* Hopefully fix the test

* Try again

* Use latest kittycad/cli version

* update gitignore and push gltf-standard into snapshot array

* Extract zipped gltf; use 8 cores for CI

* Ignore unzipped files

* A snapshot a day keeps the bugs away! 📷🐛 (OS: ubuntu)
