Deterministic zip 🗄

Regular zip utilities do not create deterministic zipfiles when given identical content. Things like the file modification times, directory iteration ordering and file permissions can change the hash of the zip file.

This is particularly annoying when using terraform with AWS Lambda. Without this tool every rebuild of the lambda source would result in a zip file with a different hash which would result in the lambda being re-deployed even if the source had not changed.
