Make a Closure Based Validator Factory

Implement make_validator(min_value=None, max_value=None, allowed_types=None, required=True) that returns a function validate(value). The returned validator should check the following: - If value is None: if required is True -> return (False, ['value required']), otherwise (True, []). - If allowed_types is provided (a tuple of types), and value is not an instance of any allowed type -> return (False, ['invalid type']). - If value is a number (int or float), min_value and max_value apply to the numeric value. - If value is a sequence (str, list, tuple), min_value and max_value apply to len(value). The validator returns a tuple (is_valid, errors) where errors is a list of string messages (possible messages: 'value required', 'invalid type', 'too small', 'too large'). Collect all applicable errors (except type mismatch should prevent range/length checks).

Practice capturing configuration in closures and producing specialized functions (validators) that enforce type and range/length constraints.

allowed_types, if provided, will be an iterable of types (you may convert it to a tuple). Do not use external libraries. Keep messages exactly as specified.
