[FEATURE] Get rid of zipped custom-pckages and use npm install instead

[Chris2011]

Is your feature request related to a problem? Please describe.
At the moment, I preinstall npm packages, upload them as a new package and after installing minifierbeans I unzip the archive. Unfortunately with the latest update there is smth broken while extracting. Sometimes it tooks too long and sometimes it seems to raise an error.

Describe the solution you'd like
I will move the custom-packages to a new folder into resources, just use the package.json and use npm install to install the latest packages in hope that this works faster and more consistent.

Describe alternatives you've considered
Alternative is to do it as it is and try to find the bug.
