Find a seed or private key to an address with a word at the beginning.
For example if you search for an address with TROLL it will search for an address like TROLL9TVCHOCOKBNWILZKMV9EKFPFBJLODURQZFSATK9RWJBUJOTTTBXJDPLPEDBLCKOVJGWFKWJYLZYDDYLTRBFNW and returns the seed/private key to it.
If only the private key is to be returned it is almost twice as fast, but you don't get a seed which you can use in Trinity.
Works with rustup default nightly-2019-04-30
