Simple Exception Handler Decorator

Exception Handler decorator allows developers to specify specific exception types to handle and provide a handler function for each of those exception types. The decorator also provides an option to specify a default return value to be used when an unhandled exception occurs. Additionally, the decorator tracks the number of times each exception type has been seen and raises a MaxRepeatedExceptionsError when a specific exception type exceeds a specified maximum number of occurrences.

The decorator uses the exception_handler function as a wrapper for the decorated function. The function accepts four parameters:

• handlers (Dict[Type[Exception], HandlerFuncType]): A dictionary where the keys are exception types and the values are the corresponding
• handler functions for those exception types.
• default_return (Optional[Any]): A default return value to be used when an unhandled exception occurs.
• max_repeated_exceptions (int): The maximum number of times an exception type can be seen before a MaxRepeatedExceptionsError is raised.
• seen_exceptions (Optional[DefaultDict[Type[Exception], List[int]]]): A defaultdict used to keep track of the number of times each exception type has been seen.

The read_env module is used to read the maximum number of repeated exceptions that can occur from an environment variable.
