Missing license text in published crate

[musicinmybrain]

Overview

The published crates lack a copy of the license text, even though the chosen MIT license requires that the copyright and permission notices “shall be included in all copies or substantial portions of the Software.”

How To Reproduce

Steps to reproduce this behavior:

1. curl -s -L https://crates.io/api/v1/crates/purl/0.1.6/download | tar -tz
2. Observe that the LICENSE file is not present in the crate

Expected Behavior

The published crate contains a copy of LICENSE

Additional Context

I plan to open a PR; the PR template asks me to crate an issue first.
