c634e4b516 chore: replace print with logging and make robot conditional
All print statements in the main program, and components used by the main program, have been replaced with appropriate logging statements. The connection to the robot now only gets made when it's possible, otherwise only the microphone will be run.

2132a74321 fix: allow access to state's exit_event while exiting
When exiting, the state's `is_initialized` flag is unset. Noticeable on Windows, when a thread tried to access the state's `exit_event` property to check whether it had been set, it would complain that the state was no longer initialized. Now, even when no longer initialized, if the `exit_event` is set, it will not raise an error when accessing this attribute.

Nothing fancy yet. When we receive a message through ZeroMQ's PUB/SUB
architecture, we tell the robot to say it out loud.

## Development environment
### Linux (or WSL)
Start off by installing [Pyenv](https://github.com/pyenv/pyenv?tab=readme-ov-file#installation) and walk through the steps outlined there (be sure to also add it to PATH). Also install the [Python build requirements](https://github.com/pyenv/pyenv/wiki#suggested-build-environment). Afterwards, install Python 2.7 and activate it for your current shell:
The robot interface is a high-level API for controlling the robot. It implements the API as designed: https://utrechtuniversity.youtrack.cloud/articles/N25B-A-14/RI-CB-Communication.

With both, if you want to connect to the actual robot (or simulator), pass the `--qi-url` argument.
There's also a `--microphone` argument that can be used to choose a microphone to use. If not given, the program will try the default microphone. If you don't know the name of the microphone, pass the argument with any value, and it will list the names of available microphones.
