Is your feature request related to a problem? Please describe.

When starting a nodejs process with pm2 using node-opcua on Windows 10 a Windows Prompt windows pops ups each time when "node-opcua-pki" package runs child_process.exec() method. The exec process is calling openssl.
There are two occurances: lib/misc/install_prerequisite.ts:98 and lib/pki/toolbox.js:123

Describe the solution you'd like

I would like to make disappear the flashing popups each time the application starts.
This could be achieved by using options windowsHide: true in exec method
Source nodejs docs

Additional context

I was able to stop the popups with editing the two js files in dist folder.
install_prerequisite.js

toolbox.js

node-opcua version: node-opcua@^2.47.0
node version: v14.17.0
Operating System: win32 10.0.19042
