shelljs dependency not installed prior to install script execution

[ryanbarr]

Upon installing node-native-ocr with npm install node-native-ocr, I was faced with the following error:

Error: Cannot find module 'shelljs'

This prevents node-native-ocr from properly installing and being added to package.json. The error is caused by the dependency shelljs here: build-tesseract.js#L3.

It seems as though the install script is attempting to use this dependency before installing the shelljs dependency. You can temporarily resolve this issue by manually installing shelljs as a devDependency with npm install --save-dev shelljs.

I'm also getting the following error:

build-tesseract script start. This script requires CMake version 3.15 or later. CMake not found on this system.

I'm presuming that any builds in Github actions won't work.
Does something like cmake-js also need to be added ?
