Option to decode JSON date string

[hongnk]

When sending Date objects, they are serialized into ISO string format, and JSON parse doesn't convert them back.

Propose to add option to JSON decode function, for example

const dateFormat = /^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}\.\d{3}Z$/;

function dateReviver(key, value) {
    if (typeof value === "string" && dateFormat.test(value)) {
        return new Date(value);
    }

    return value;
}

module.exports.decode = function(str) {
     return JSON.parse(str, dateReviver)
}

How about adding EJSON support?
