allow namespaces

[chris-aeviator]

the original exec comes with a handy namespace. it allows for the addition of trusted extra code

     # Dictionary to store definitions from the script
    script_namespace = {'myFunction': myFunction}

    # Execute the script within the module's namespace
    exec(script_content, script_namespace)

it would be handy to allow for extra functions to be imported within the execution context

Hmmmm. I'm not certain as to how implement this. I believe the args passed to the WASM execution environment are converted to string representations. I'll take a look at this further. Thanks for opening this!
