* We used several utility functions to parse frostfsid client subject and extended subject. However, following the changes in TrueCloudLab/frostfs-contract#97, these utility functions have become public. So there is no more need to have them here. * There was a mismatch of slice parameter required length between frostfs-node's and frostfs-contract's utility functions, `checkStackItem()` solves this problem.
