GeoStyler Data Parser implementation for Web Feature Services (WFS)

Please provide related issues here https://github.com/geostyler/geostyler/issues

Currently, WFS service must support application/json as outputFormat and its application server must be configured to send CORS headers (only needed if WFS Service is not located on the same origin as the component using this parser)

Maintenance and further development of this code can be funded through the GeoStyler Open Collective. All contributions and expenses can transparently be reviewed by anyone; you see what we use the donated money for. Thank you for any financial support you give the GeoStyler project 💞
