🐛 Casting new types requires manual interaction

[0xKiwi]

This plugin relies on a very naive name check -> casted type for casting what is needed. This means if there are any need types required to cast, they will need to be manually added here. I propose we add a function to eth2-types to make these types less separated.

For some reason this is where comments to

replace github.com/grpc-ecosystem/grpc-gateway/v2 => github.com/prysmaticlabs/grpc-gateway/v2 v2.3.1-0.20210524202756-cefc26c3f2bf

point.

Anybody have a better way to document this?
