the snowhash link 404's

[amy-keibler]

The link to snowhash in the visualization section points to a personal webpage. It appears that the author has moved the post from https://joshleeb.com/projects/snowhash/ to https://joshleeb.com/posts/rust-wasm-snowhash/ with a git repository for the project located at https://github.com/joshleeb/snowhash-wasm.

Would the desired update be for the link to point to the github project and for users to find the article via its README.md? If so, I'll make a pull request with that change.

Thanks for the list of Rust+WASM resources!
