Commit Cargo.lock changes, add build scripts (#1521)

## Issue Addressed

NA

## Proposed Changes

This PR commits the `Cargo.lock` file so it does not indicate a dirty git tree in the version tag. This code should be used for the `v0.2.3` release.

Also, adds a `Makefile` command to produce tarballs for upload on release.
