Accept only keys defined in rule object

[bytemerger]

I am using the version 3.22.1

Could it be possible to have a feature where the validator can return an error if data key with that is not defined in the rule is passed
for instance

const validator = new Validator(req.body, {
        name: 'string',
        body: 'string',
    });

The above should return an error if req.body contains more object keys than defined in the rule

A solution could be to add a third instance parameter to new Validator(data,rule,strict)
strict would either be true or false.
This would mean whether the validator should follow the rule strictly not allowing additional keys or not.
