devDependencies defined in package scripts not detected.

Thank you for this wonderful tool. However, depcheck seems to think that my project is not using standard, yet it is used in my package scripts:

{
  "scripts": {
    "start": "node app",
    "test": "npm run check-style && (istanbul cover --include-all-sources tape -- '!(node_modules)/**/*.test.js' | tap-dot) && npm run check-coverage && npm run check-security",
    "quick-test": "tape '!(node_modules)/**/*.test.js' | ./node_modules/.bin/tap-spec",
    "check-test": "istanbul cover --include-all-sources tape -- '!(node_modules)/**/*.test.js' | tap-dot",
    "check-security": "nsp check",
    "check-coverage": "istanbul check-coverage",
    "check-style": "standard",
    "lint": "standard"
  }
}

Many thanks,

I am experiencing the same a lot of times. Here is one example where nodemon is considered unused.
package.json:

"scripts": {
    "build": "tsc -p src/",
    "build:watch": "tsc -p src/ -w",
    "watch": "concurrently \"npm run build:watch\" \"nodemon app.js\"",
    "start": "node app.js",
    "lint": "tslint ./src/**/*.ts -t verbose"
}
