Implement `IsOwner` and `IDEquals` functions which check the
correspondence of the fields in `Info`. Remove no longer needed
`HasOwner` method of `Info`.

Create `subnet` package. Define `Info` type of the subnet info. Support
encoding and transport over the NeoFS API V2 protocol. Add methods to
work with identifier and owner.

* Implement `NodeInfo.EnterSubnet` method which adds node's subnet.
* Implement `NodeInfo.IterateSubnets` which behaves similar to
eponymous function from neofs-api-go/v2.
* Implement `BelongsToSubnet` which checks if `NodeInfo` describes the
node belonging to a specific subnet.

Create `subnet` package. Define `ID` type of subnet identifiers.
Implement encoding and support NeoFS API V2 protocol. Provide method to
init instance from integer. Implement function which checks if `ID`
instance refers to zero subnet.

Make all `Client` methods to return structured values and error. Parse v2
status messages in all RPC and provide status getter from all result
structures. Returns status failures as status result instead of error.
Interface changes:
* all methods return `<method>Res` structure;
* rename some methods to be more clear;
* unify TZ and SHA256 objecy payload hashing in single method.
Behavior changes:
* client doesn't verify object header structure received via Object.Head.
If the caller was tied to verification, now it must do it explicitly.

Define base `Status` interface. Provide the functionality to distinguish
success and failure returns. Provide functionality to transport statuses
over NeoFS API V2 protocol. Support success `OK` and failure `INTERNAL`
returns.

Change `Marshal` signature to `Marshal() ([]byte, error)`.
Dependency update in SDK itself should be done after moving client
as `pool` package has some dependent function signatures.

Another possible panic (though quite rare).
