[Feature Request] Adding TTL to records

[MrMagicPickle]

Hello, I'd like to request to add an easy means of adding TTL to our records so that they can be automatically deleted after they reach an expiry datetime.

The reason I am proposing this is because:

I foresee that one of the common usecase for applications that use instantDB would be to create a quick realtime collaborative environment as a one-time-use, but then never re-visit it again. For example: multiplayer lobby games, temporary file sharing links, online polls/surveys, etc.

Having an expiration property on the records would be helpful and convenient.
