Support for Filter Predicates #313

Question

A QML rule such as:

<rule scalemaxdenom="25001" label="public building" filter="&quot;type&quot; IN ('kindergarten', 'civic', 'government', 'hospital', 'school', 'train_station', 'transportation', 'university', 'public', 'toilet', 'religious', 'cathedral', 'chapel', 'church', 'mosque', 'temple', 'synagogue', 'shrine', 'supermarket', 'kiosk', 'retail', 'shop')" description="Gebäude die grundsätzlich öffentlich zugänglich sind; z.B. Schulen, Kirchen, Supermärkte, Ämter, ..." key="{025f854c-d5b6-42f4-b73f-ca62e338cc3c}" scalemindenom="1" checkstate="0" symbol="0"/>

Gets turned into a GeoStyler rule in the form:

  "rules": [
    {
      "name": "public building",
      "filter": {
        "type": "InExpressionListPredicate",
        "hasNot": null,
        "left": "type",
        "right": [
          "kindergarten",
          "civic",
          "government",

I've searched for predicates such as InExpressionListPredicate in the GeoStyler parsers, but get no matches. Are these predicates currently not supported, and need to be added to the individual parsers?

@KaiVolland could you take a look at this?

The created filter in geostyler-style does not look like our filter format. Maybe we have to adjust the jison in the geostyler-cql-parser to create a proper structure for that case.
