Better keyHashToText and scriptHashToText reuse in command

[paweljakubas]

Context

We have hrp definition in scriptHashToText and keyHashToText but in some command, which should use them, we have redefinition of them, ie. duplication. Also in Cardano.Address.Script we have both script, script hashes and key hashes. Which is not so good domain separation.

Decision

1. We have separate module Cardano.Address.KeyHash
2. In Command.Key.Hash we resign from redefining of hrp transitions but reuse what is in keyHashToText
3. Extend KeyRole to include PaymentShared and DelegationShared
