This module contains functions which are used for Large Object assemling:
getting Last Object and split and getting Link Object. It is not enough to
simply perform a "raw" HEAD request, as noted in the issue:
https://github.com/nspcc-dev/neofs-node/issues/1304. Therefore, the reliable
retrival of the aforementioned objects must be done this way: send direct
"raw" HEAD request to the every Storage Node and return the desired OID on
first non-null response.
