- Update `neofs-sdk-go`: v0.0.0-20211230072947-1fe37df88f80 => v0.0.0-20220113123743-7f3162110659 - Add client interface that duplicates SDK's client behaviour and new `MultiAddressClient` interface that has method that iterates over wrapped clients. - Also start using simple client mode that does not require parsing statuses outside the SDK library.
