The LICENSE file carried over from the standalone repo was MIT, while
Cargo.toml declares Apache-2.0, the workspace this crate was extracted from
is Apache-2.0, and the website says Apache-2.0. The one file a reader opens
to check was the only place saying otherwise.
Replaces it with the full Apache-2.0 text and adds the matching NOTICE, both
taken from the monorepo root where they were already correct.
Caught before the repository was made public.
