Enhancement: Improve installation process

[s1hofmann]

Short overview
Current installation process takes way to long

Use case
Faster installation / time to first test

Detailed description
Currently, nut.js builds OpenCV from source by default.
This installation process takes quite a while and requires external tooling (cmake).
As a user I don't want to compile a OpenCV via cmake when installing nut.js

The first approach was to reduce lib size and prebuilt OpenCV. Further enhancement would be portable, prebuilt bindings
