Feature: Time travel queries

[Simon0x]

This is a concept that is coming from TheGraph and very useful in my opinion.
This way we would not need to define extra schema entities to keep track of historic times. Like saving them hourly or so. Rather we can specify a block number in the query and get the state at that moment.

Hi, @Simon0x , sorry for leaving comment here without your agreement and respecting the team rule. Because I wanna contribute to Envio team's development and join your team, so I am going to solve issues. So could you give me some issue to be solved quickly as test task?

Hey @solthereum, I'm not part of the envio team. I suggest you to join the envio discord and talk more with the team over there. They are very active.
