No option to recover public key from signature. #38
Description
While the recovery info can be encoded in the signatures and parsing of signatures with recovery info is supported, it currently isn't actually possible to verify a signature with recovery info without still suplying a public key first.
Either the verify function should work without an explicit public key, or the signature should allow the public key to be extracted from it so that public key could be handed to the ecdsa verify.
(This issue is related to #37 in that the functionality I need to implement in this project has recovery info in signatures AND a public key that is compressed. If either of these issues were solved validation would be possible.)
