665e5807bc [#188] transformer: Allow to provide size hint 
For big objects with known size we can optimize allocation patterns
by providing size hint. As with any hint, it does not affect transformer
functionality: slices with capacity > MaxSize are never allocated.

The code of frostfs-node is not yet ready to reuse egress target for
multiple objects, let's postpone until #64.
