Raw Value serializer output json string for Spatial type

Issues

• Raw value serializer for Spatial type not correct #846

Description

In RawValueWriter.cs, There's a function named WriteRawValue(object value), in which it has the following codes to write the Spatial object:

else if (value is Geometry || value is Geography)
{
   PrimitiveConverter.Instance.TryWriteAtom(value, textWriter);
}

However, it should call WriteJsonLight, not TryWriteAtom.

For example:

RawValueWriter target = new RawValueWriter(this.settings, this.stream, new UTF32Encoding());
var value2 = GeometryPoint.Create(1.2, 3.16);
target.WriteRawValue(value2);

Expected result

{"type":"Point","coordinates":[1.2,3.16],"crs":{"type":"name","properties":{"name":"EPSG:4326"}}}

Actual result

RID=4326;POINT (1.2 3.16)
