you cannot `trunk serve` the example app out of the box

[duckfromdiscord]

There is no index.html for trunk to use when you first clone this repo. To build the example app for WASM, trunk requires an index.html and a couple dependencies. There seems to be some functionality in the code already for WASM but it is unfinished and we cannot build for WASM.

This change here makes it so that you can clone the repo, move into the example app folder, and trunk serve right away: https://github.com/duckfromdiscord/ewebsock/commit/0b7938d0411f1b8048b2b687c3a3d00202a02a67

Feel free to make a PR to make it easy to compile with trunk
