This is less appropriate for this mode :
benchmark is about accuracy,
it's important to read the exact values.

As a library, the default shouldn't be to write anything on console.
`cover` and `fastcover` have a `g_displayLevel` variable to control this behavior.
It's now set to 0 (no display) by default.
Setting notification to a higher level should be an explicit operation by a console application.

small general compression ratio improvement for btopt+ strategies/

used to be necessary to counter-balance the fixed-weight frequency update
which has been recently changed for an adaptive rate (targeting stable starting frequency stats).

better for larger blocks,
very small inefficiency on small block.

better for large files, and sources with relatively "stable" entropy,
like silesia.tar.
slightly worse for files with rapidly changing entropy,
like Calgary.tar/.

Updated small files tests in fuzzer

notably within kernel space

by employing parallel compilation of object files.
