feat: adds s3 workflow

[jtyoung84]

Closes #2

• Adds script to build metadata file, rename folder, upload folder to s3, and registers the data asset to code ocean
• A bit of a hack, but should work until we can write directly to s3
• Uses git to check which files were added in the most recent commit, and then uses that information to drive the rest of the python script.
• Will need to manually do a bulk upload before the pr is merged.
