name: Download artifact
description: Wrapper around GitHub's official action, with additional extraction before download

# PROCESS
#
# 1. Downloads artifact using actions/download-artifact action
# 2. Extracts and overwrites tarball previously uploaded
# 3. Remove archive after extraction

# NOTES
#
# Upload-artifact and download-artifact takes ~2m40s to upload 8MB
# so this is custom action cuts down the entire operation to 1s
# by uploading/extracting a tarball while relying on the official upload-artifact/download-artifact actions
#

# USAGE
#
# NOTE: Meant to be used with ./.github/actions/upload-artifact
