to-values 0.1.0

Flatten values into ordered f32 feature vectors.
# Publishing

This workspace contains two crates. `to-values` re-exports the optional
procedural macro from `to-values-derive`, so the macro crate must be published
and indexed first.

1. Update versions, release notes, and the minimum supported Rust version when
   appropriate. Keep the exact `to-values-derive` dependency version in the
   root manifest synchronized with the derive crate's version.
2. Verify the workspace locally:

   ```sh
   cargo fmt --all -- --check
   cargo clippy --workspace --all-targets --all-features -- -D warnings
   cargo test --workspace --all-features
   cargo test -p to-values --no-default-features
   cargo doc --workspace --all-features --no-deps
   ```

3. Inspect and fully verify the independently publishable derive crate:

   ```sh
   cargo package -p to-values-derive --allow-dirty
   ```

4. Publish `to-values-derive` and wait until crates.io has indexed it:

   ```sh
   cargo publish -p to-values-derive
   ```

5. Package and publish the facade crate. At this point Cargo can resolve and
   fully verify its newly published dependency:

   ```sh
   cargo package -p to-values
   cargo publish -p to-values
   ```

Use `cargo publish --dry-run` in place of either publish command when doing a
final pre-release check. Do not use `--allow-dirty` for an actual release.
