Encrypted Inputs

Note that inputs are included in the repository so that they can be used in CI, but they are encrypted using git-crypt. To use this repository on a new machine, you will need access to the base64 encoded key, then you can run:

echo $GIT_CRYPT_KEY | base64 --decode > git-crypt.key
git crypt unlock ./git-crypt.key
rm ./git-crypt.key
