✨ `validated()` method #444

✨ validated() method

Fixes #307

Description

This PR adds two methods to Validator's prototype; validated() and _onlyInputWithRules(). Inspired from Laravel's validation concepts.

validated() method will retrieve the input data without the attributes not defined in rules provided. This helps to extract only valid dataset from input and filter out unnecessary or additional attributes from input.

While validated() throws an error if the validation fails, _onlyInputWithRules() does the pure job to filter out non-listed-in-rules attributes. validated() method relies on _onyInputWithRules() method under the hood.
