alexvanin 1958ff8c37 Use NEO3 based address generation
With neo-go v0.90.0 there are new event subscription component
and new verification script routines based on NEO3. These features
allow to avoid using low-level neo-vm code in NeoFS and corresponding
projects.

This commit removes unused function:
- FetchPublicKeys (used in neofs indexer),
- VerificationScript (used in KeysToAddress),
- Address (used in KeysToAddress),
- ReversedScriptHashToAddress (used in neofs indexer),
- IsAddress (used in neofs indexer),
- ReverseBytes (used in neofs indexer),
- DecodeScriptHash (used in neofs indexer).

KeysToAddress changed into KeyToAddress because NeoFS won't work with
multisignature owners for now and it is not supported in neo-go library.
