Add reading STDIN and writing to STDOUT tests

[guest271314]

Thinking about writing a generic, runtime agnostic Native Messaging host in JavaScript targeting WASM. I'm curious what the JavaScript code that componentize-qjs expects and WIT file will look like. For example, the generated WIT produced by wasm-tools for AssemblyScript https://github.com/guest271314/native-messaging-webassembly/blob/main/nm_assemblyscript_component.wit and Bytecode Alliance's Javy https://github.com/guest271314/native-messaging-webassembly/blob/main/nm_javy_component.wit components that implement the same algorithm contain different content.

Hey, I've added some examples of echo component using wasi p3 here:

https://github.com/andreiltd/componentize-qjs/blob/main/tests/wasi.rs#L225

Let me know if that works for you.
