Classes are mostly done. Need to finish CLI and write some documentation (docstrings look like a must at this point).

Now it's time to do the CLI yay

The synchronous 'change_source' method calls the async functions '__close_cap' and '__open_cap' without awaiting them. Consider converting 'change_source' into an async function and using 'await' when calling these functions to ensure proper execution.
