Support for custom electron fork

[dowmeister]

Hi,

i'm developing an app using a forked Electron version, specifically the ow-electron package, https://www.npmjs.com/package/@overwolf/ow-electron

Also setting the electronPath in electronmon packages.json section, doesn't seem nodemon is starting using ow-electron

 "electronmon": {
    "patterns": [
      "!**/**",
      "src/main/**"
    ],
    "logLevel": "verbose",
    "electronPath": "./node_modules/bin/ow-electron"
  }

tried with simple ow-electron also.

I'm using it with the electron-react-boilerplate https://github.com/electron-react-boilerplate/electron-react-boilerplate

Replacing electromon with ow-electron here, launch the application with ow-electron

"start:main": "cross-env NODE_ENV=development electronmon -r ts-node/register/transpile-only .",

I'm not an Electron expert so probably i'm missing something :)
