func TextAndHash 

func TextAndHash(data []byte) ([]byte, string)

TextAndHash is a helper function that calculates a hash for the given message that can be safely used to calculate a signature from.

The hash is calulcated as

This gives context to the signed message and prevents signing of transactions.
