[ #229 ] blobovnicza: Store objects in a binary format
...
In previous implementation Blobovnicza's stored objects in protocol format
which did not allow working with externally compressed objects. To achieve
this goal, operations Get and Put no longer work with the structure of the
object, but only with abstract binary data. Operation GetRange has become
incorrect in its original purpose to receive the payload range. In this
regard, BlobStor receives the payload range of the object through Get
operation. In the future either Blobovnicza will learn to compress objects
by itself, or the GetRange operation will be eliminated.

depth is zero, the blobobnivza will be in the root path. Fix negative

Using 2 bytes length for directories in fs tree lead to large growth
in the number of directories.

[ #176 ] shard: Fix BlobStor access when data range is zero
...
In previous implementation Shard accessed the BlobStor to get the
object header. However, the shard must take headers from the metabase.
From now zero length of the requested payload range seens as object
header request. In this case shard calls metabase to get the header.

[ #176 ] blobstor: Handle error of zstd (de)compressor creation
...
In previous implementation WithCompressObjects returned Option
than could panic if zstd (de)compressor creation failed with error.
From now errors with (de)compressor creation result in an option
without using data compression. In this case, the error is written
to the log passed to the option constructor.

[ #176 ] localstore: Change multiple access sync
...
In previous implementation each operation on local storage
locked engine mutex. This was done under the assumption that
the weights of the shards change as a result of write operations.
With the transition to static weights of shards, it is no longer
necessary to lock the global mutex during the execution of operations.
However, since the set of engine shards is dynamic, there is still a
need to control multiple access to this set. The same mutex is used
for synchronization.
