Leonard Lyubich f194c840d7 [] 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.
