Add WASM interaction layer

[AndyTitu]

🦾 Reason to Be

Add logic for interacting with the WASM core. The core was built using wasm_bindgen.

🤔 Thought Process

The js-core folder was built from Rust using wasm_bindgen for generating an additional JS wrapper.

📋 How To Test

Run npm start from the root of this repo to run the provided example. This will run the examples/index.ts code (Make sure you're using the SA token and valid integration details).

Under the hood npm start will compile TS to JS using tsc and then will run the produced index.js file with node.

Given the current approach of calling WASM functions from JS (using ES imports), there are a few limitations I ran into:

• I couldn't find a way to run this code from the terminal unless I used the method described in How To Test. @jodyheavener do you know if another way exists? I tried using ts-node but I kept running into other issues.
• I had to add the .js extension in all the ES imports because otherwise node couldn't resolve them. @jodyheavener again, this is something that I'd like to avoid.
• From what I found people will have to use at least Node 20 for using the SDK. I think this is independent of the current approach for importing WASM functions.

Closing this in favour of a new approach for distributing wasm files.
