Add serve command to build and serve static files

- needed an http server to serve 'wasm' extension
- I typically use nginx in one-time docker container run mapped to local directory to serve files
  - needed to add custom nginx config to serve "application/wasm" mime type
- interested in adding info to Yew docs, looked at website which I then looked at Rollup example source
  - they recommend using python http server
- found myself on Rust WASM RFCs github page with "watch and serve" command RFC
  - rustwasm/rfcs#10
