Please provide license text

[michel-slm]

I'm packaging this as a dependency of miette in Fedora, and our guidelines strongly prefer that source archives (in this case, crates) come with the license text(s) for the software: https://docs.fedoraproject.org/en-US/packaging-guidelines/LicensingGuidelines/#_license_text - in fact, in the case of the MIT license, the license itself requires including the text with all derivative works.

Please consider adding this to the GitHub repo and referencing it from Cargo.toml in future releases - as long as the license is in the repo, that will unblock packaging, thanks!
