 Each index file is an object containing a constant-sized batch of raw block object
 IDs in binary form ordered by block index. Each index file is marked with the
 following attributes:
  - index file identifier with consecutive file index value (`Index:0`)
  - the number of OIDs included into index file (`IndexSize:128000`)
+ - second-precision index file uploading timestamp (`Timestamp:1627894840`)
