Create a test utilities for Eureka packet parsing, similar to what we have here:

I would imagine we would need to rename and refactor a bit to make a clear distinction between the type of packet your expecting. So either parsing for an IBC v1 packet (the current functions) or an IBC v2 packet.

Replace any places where we manually find the packet data or sequence today with the new test utilities method(s).

ℹ️ There is an implementation that may be possible to use as a starting point here: https://github.com/gjermundgaraba/libibc/blob/341e29c8dad60f63af2006425c3245f3aa69d343/chains/cosmos/events.go#L82-L109
