Add ability to install eversdk/lib-web package without running postinstall scripts

[awnion]

@eversdk/lib-web package includes post-install scripts. As a security best practice, it's generally a good idea to install npm modules with the --ignore-scripts flag to prevent any potentially malicious code from being executed. It would be great if the option to skip these scripts could be added to the package in the future. Just wanted to pass this suggestion along in case it's something that could be implemented.
