Leonard Lyubich ed80f704d0 [#556] innerring/neofs: Process Bind/Unbind events
Make IR processor of NeoFS contract to handle `Bind`/`Unbind` notification
events. The processor verifies the format of wallet script hash and public
keys, and call NeoFS ID client wrapper in order to approve adding/removing
keys from NeoFS account.
