Internally, only used by reth-discv4 in EnrWrapper.

[mattsse]

this is tough, because we need this to decode Enr which can only be decoded via rlp -.- the only workaround would be to use the EnrBuilder type, but this would be pointless since the enr crate already pulls in the rlp crate, so we can reuse it for free
