Current behavior

You are not allowed to provide an array of source paths for icon generation, it was possible before your own svg-generator.

Expected behavior

You can provide an array of source paths for icons.

Minimal repoduction

old:

"svg-to-ts": {
    "conversionType": "object",
    "srcFiles": [   
      "./src/assets/svg/*.svg" ,
     "./node_modules/some_lib/assets/svg/*.svg"
    ],
    "outputDirectory": "./src/assets/svg",
    "fileName": "svg-icons",
    "svgoConfig": {
      "plugins": [
        {
          "removeDimensions": true,
          "cleanupAttrs": true
        }
      ]
    }
  }

new:

"svgGenerator": {
    "outputPath": "./src/app/svg",
    "prefix": "app",
    "srcPath": "./src/assets/svg", // Array will throw error
    "svgoConfig": {
      "plugins": [
        {
          "removeDimensions": true,
          "cleanupAttrs": true
        }
      ]
    }
  }

What is the motivation/use case for changing the behavior?

For example generation of icons from node_modules and project assets.

You can add a nameNormalizer function that returns a modified name if you want.
