Implement hooks system

[D34DPlayer]

CRUD?
EventEmitter?

DB events

• "close": https://developer.mozilla.org/en-US/docs/Web/API/IDBDatabase/close_event
• "populate": first creation
• "ready": the open succeded (does it make sense with the explicit init?)
• "versionchange": the db is being updated elsewhere (usually inform user to save anything and tell them to reload)

Table events

Extra

Could we use BroadcastChannel, so that changes on any tab trigger hooks on every tab? It should be clear where the action actually takes place to do actual modifications rather than just listening in:

// Will trigger only if action in current tab
User.hook("beforeUpdate", async (element) => {
    element.version += 1
})
// Will trigger on all tabs
User.hook("afterUpdate", async () => {
    fetchUsers()
})
