Syncing events with Date value

[deskoh]

Events are currently serialized using JSON.stringify. Since Date values are not supported in JSON (see here), it will be converted to string. When received, the value will be converted to a string when serialized. This will be 'lossy', in particular, milliseconds accuracy is lost.

const date = { date: new Date() }

// {date: Mon Oct 21 2019 21:41:56 GMT+0800 (Singapore Standard Time)}
console.log(date)

// {date: "2019-10-21T13:41:56.915Z"}
console.log(JSON.parse(JSON.stringify(date)))

I'm wondering if there should be a way to provide a custom serializer/deserializer. There is probably other cases where you want to convert things. This would also take care of #87

This can now be done in v1.2.0 and later by using a custom serializer/deserializer.
