The result of the custom validator lost a property `field`.

Hello,

Thank you for this open source project. I use fastest-validator on my websites.

I found an issue about the custom validator.
The result of the custom validator lost a property field.

<script src="https://unpkg.com/fastest-validator"></script>

let v = new FastestValidator({
    messages: {
        // Register our new error message text
        weightMin: "The weight must be greater than {expected}! Actual: {actual}"
    }
});

const schema = {
    name: { type: "string", min: 3, max: 255 },
    weight: {
        type: "custom",
        minWeight: 10,
        check(value, schema) {
            return (value < schema.minWeight)
                ? [{ type: "weightMin", expected: schema.minWeight, actual: value }]
                : true;
        }
    }
};

console.log(v.validate({ name: "John", weight: 8 }, schema));

[
  {
    "message": "The weight must be greater than 10! Actual: 8",
    "type": "weightMin",
    "expected": 10,
    "actual": 8
  }
]

It should be:

[
  {
    "message": "The weight must be greater than 10! Actual: 8",
    "type": "weightMin",
    "expected": 10,
    "field": "weight",
    "actual": 8
  }
]
