def _should_be_async ( cell : str ) → bool

Detect if a block of code need to be wrapped in an async def

Attempt to parse the block of code, it it compile we're fine. Otherwise we wrap if and try to compile.

If it works, assume it should be async. Otherwise Return False.

Not handled yet: If the block of code has a return statement as the top level, it will be seen as async. This is a know limitation.
