How to run with .svgtofontrc?
I am unable to run this with the configuration file

My .svgtofontrc is located in the root folder of the nodejs project?

```json{
  "fontName": "svgtofont",
  "css": true,
  "src": "svg",
  "dist": "fonts"
}
```

`yarn svgtofont` -> prints out help and `Missing required arguments: output, sources`
Also no option to select  a custom config file, like `yarn svgtofont --config/-c path/to/config/config.json`

Isn't it possible to set all properties in the config file?
There is also no feedback if the configfile is used?

I got it running with the typescript way and with the package.json configuration, 

It would be nice for me, someone can tell me what i'm doing wrong :)
