Custom event class

[HigherOrderLogic]

Describe the feature

I notice that some functions (not all) have event type generic.

So is it possible for user to use their own custom event class provided to createApp?

Example:

class MyEvent extends H3Event { ... }

const app = createApp({ eventClass: MyEvent })
