Do some include shuffling for `**.h` files within lib, programs, tests, and zlibWrapper.
`lib/legacy` and `lib/deprecated` are untouched.
`#include`s within `extern "C"` blocks in .cpp files are untouched.
todo: shuffling for `xxhash.h`
After a regrettable update,
the benchmark module ended up reloading sources for every compression level.
While the delay itself is likely torelable,
the main issue is that the `--quiet` mode now also displays a loading summary between each compression line.
This wasn't the original intention, which is to produce a compact view of all compressions.
This is fixed in this version,
where sources are loaded only once, for all compression levels,
and loading summary is only displayed once.
this generator replaces the statistical generator
for the general case when no statistic is requested.
Generated data features a compression level speed / ratio curve
which is more in line with expectation.
