Motivation

People may want to compile ROHD into WASM (https://dart.dev/web/wasm).

Note that the "WASM compatibility" score will be affected in the future on pub.dev: https://pub.dev/packages/rohd/score

We already have javascript compilation and testing in the repo to make sure ROHD can run in javascript environments. We should add WASM as well.

Desired solution

Add WASM support and test as part of CI
