Improve CI for web targets (#108)

* Simplify CI process for WASM

Run WASI tests, and run both stdweb/wasm-bindgen on both node and in browsers

These changes also remove the need for a separate tests/wasm_bindgen

* Use all pre-built binaries in the CI

* Fix Cargo.toml typo

Co-Authored-By: Artyom Pavlov <newpavlov@gmail.com>

* Fix install location

* Debug CI
