Create context manager that allows a loop to be interrupted early

[nathan-hess]

Major Changes and Improvements

• Created a context manager pyxx.dev.InterruptibleLoop that allows (possibly long-running) loops to be exited early by pressing Ctrl+c
  • This can be useful in cases such as training a machine learning model, when it may be desirable to stop training partway through (based on observed losses) but the script needs to gracefully end (saving data, generating figures, etc.) rather than immediately terminating
  • Handling SIGINT is a convenient way to accomplish this as it is simple and intuitive
• Added unit tests and documentation for new class
