Adds a helper function to recover from panics and automatically adds relevant key-values, like operation, code, severity and file where the panic occurred.

The DontPanic function will add and operation for the panicking function with file and line number.

The key-value format was change to key=value instead of key: value for better readability.

• Switching the key-value separator from “:” to “=” in error messages.
• Adding the new DontPanic function and associated tests to safely recover from panics.
