@benliao Thanks very much for your contribution, it's greatly appreciated! 😄 It's great to have WASM support for the noise filters. I'm just wondering if you could run cargo fmt on the directory so that the formatting test will pass. I will then merge your contribution ✅

@silvia-odwyer, sorry for missing run "cargo fmt" the new commit has run cargo fmt and no modification to cargo.toml, with contributor information in the readme. thanks.

@silvia-odwyer The noise function has been added to the webpack demo, the cargo test passed, and the cargo formatted. The add_noise_rand function parameter and return changed to work with the webpack demo and aligned with other interfaces.
