4.0.0 + Gretch Jazzkit and 3 more kits

Drumlabooh 4.0.0

What's new?
The first and visible one - "Analog" saturator slider at the main screen, applied to the whole mix at the end of the signal flow. Move the slider to make tiny and weak drums bigger and stronger, if that you need.
This version also introduces new multi-sampling mode, where the engine plays sample layers according to MIDI velocity, but the velocity's value is not included to the final signal calculation formula. It's useful when we have too quiet sampled layers. Read https://github.com/psemiletov/drum_sklad for the details of such option at the drumkit.
New compilation flag for the packagers - use cmake -DINSTALLKITS=OFF to disable fetching and installing the drumkits, so now you can build just the package with the binaries, and make separated package with kits from https://github.com/psemiletov/drum_sklad/archive/refs/heads/main.zip
Speaking of the kits. Now you can place them also to $HOME/drum_sklad (to simpilify keeping them up-to-date in the case of the manual installing/updating via git).
And, the new kits:
