BlobStor constructor. Implement Open/Init/Close methods.

There is a need to support single blobovnicza in blobovnicza tree. This can
be achieved with a width of 1, and a depth of 0 or 1. With depth = 1 one
redundant directory is created, inside which there is a blobovnicza. If the
depth is zero, the blobobnivza will be in the root path. Fix negative
capacity in iterateDeepest method with zero depth.

Place the root of blobovnicza tree in a subdirectory of BlobStor with same
permissions. Abolish WithBlobovniczaRootPath and WithBlobovniczaPersmissions
options.

Blobovnicza ID parameter provides the ability to specify particular
blobovnicza to delete object from. In this case only specified blobovnicza
is processed.

In previous implementation objects were classified by size according to
payload size. From now they are classified by the size of their binary
representation.

Implement "big or small" property classifier (only the size of the payload
is temporarily considered). Save "big" objects in shallow dir. Save "small"
objects in shallow dir until the moment of implementation of blobovnicza.

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.

Correct the calculation of maximum value of fs tree depth. Fix check
of the max depth overflow in WithShallowDepth function.
