WASM support

[kgv]

Unfortunately, there is no support for WASM.
This issue is just to track the status of this enhancement.

#502 (comment)

am not wrong, you are building for the wasm target, which we haven't as of yet started supporting. We can keep this issue open and see if anyone gets to it in the future, but I don't expect much movement for a while.

FWIW, since tokio was linked,
tokio supports websockets in WASI (wasm32-wasi target) with the net feature and tokio unstable enabled (RUSTFLAGS="--cfg tokio_unstable")
