Leonard Lyubich 1c30414a6c [] Upgrade NeoFS SDK Go module with new IDs
Core changes:
 * avoid package-colliding variable naming
 * avoid using pointers to IDs where unnecessary
 * avoid using `idSDK` import alias pattern
 * use `EncodeToString` for protocol string calculation and `String` for
  printing
