[ #1317 ] go.mod: Use range over int
...
Since Go 1.22 a "for" statement with a "range" clause is able
to iterate through integer values from zero to an upper limit.

[ #754 ] blobstor: Estimate compressability
...
Now it is possible to enable compressability estimation.
If data is likely uncompressable, it should reduce CPU time and memory.

[ #2184 ] compression: Properly calculate upper bound
...
If the data is not compressible allocating `len(data)` will lead to a
slice reallocation. For a compressible data the results for small size
are flaky and we allocate a bit more. However, it feels right to use a
provided function if we need to pick any size at all.
