dev: Implement the Aggregation Hook contract

[JordyRo1]

Issue

In order to understand what hooks are, here are some (additional informations)[https://docs.hyperlane.xyz/docs/reference/hooks/overview]. Are already implemented the merkle tree hook and the protocol fee hook. The goal here is to implement the aggregation hook, which will allow multiple hooks to be used at the same time.
