Add the necessary `Cargo.toml` magic for `cargo test` to build `#[test]` and `#[proptest]` tests correctly. However the wasm test harness ignores `#[test]` and `#[proptest]`, so tests are not actually run on wasm targets when running `cargo test`. Instead, use the `#[wasm_bindgen_test]` annotation to enable tests on wasm targets. Also enables compilation on 32-bit architectures by correcting the NTT's `NUM_DOMAINS` to 29 on 32-bit systems. It remains unchanged at 32 on 64 bit systems.
The crate is unmaintained and, for the purpose of testing on wasm32, unusable. Because 1. the code has seen very little activity since its inception, 2. there are only a little more than 100 lines of code, and 3. it has worked perfectly well for all our needs so far, I think the risks associated with inlining are acceptable.
