tokio blocks wasm-unknown-unknown & ∴ wasm-pack & wasm-bindgen

web takeaway for the day: tokio doesn't support wasm32-unknown-unknown. will have to use wasm32-unknown-wasi, which tokio supports. i don't think wasm32-unknown-emscripten is going to help
so: skip the wasm-pack and wasm-bindgen crates, which use wasm32-unknown-unknown
see rustwasm/wasm-bindgen#3421
probably no big deal and other tools will work, this was just the first resource I tried
