[#537] Upgrade NeoFS SDK Go with changed netmap package

Browse source 
`PlacementPolicy` type now provides methods to work with QL-encoded
policies. System network parameters can be read using dedicated method
without iterating. Applications can work with `PlacementPolicy`
variables directly so there is no need to use pointers.
