From 34a221c5c95569465037ed846acdc9b3526f3057 Mon Sep 17 00:00:00 2001
From: Leonard Lyubich <leonard@nspcc.ru>
Date: Tue, 8 Feb 2022 19:54:04 +0300
Subject: [PATCH] [#346] Upgrade NeoFS SDK Go library

Core changes:
  - `object.ID` moved to new package `oid`;
  - `object.Address` moved to new package `address`;
  - `pool.Object` interface changes.

Additionally:
  - Set container owner in `Agent.IssueSecret`.
  - Remove no longer needed fields from `GetObjectParams`
  - `Length` and `Offset` are never assigned. These values
  are set in `Range` field.
