Mapping of byte and short types in MapFromAttributes

[michaeljmx]

We are using the MapFromAttributes method to create Elasticsearch mapping from classes. We have found out that it doesn't work with properties that have byte and short types.

I've checked the library sources and found out that there is really no support for these types. Here is the part of the GetFieldTypeFromType method from file TypeMappingWriter.cs:

switch (propertyType.Name)
{
    case "Int32":
        return FieldType.Integer;
    case "Int64":
        return FieldType.Long;
    case "Single":
        return FieldType.Float;
    case "Decimal":
    case "Double":
        return FieldType.Double;
    case "DateTime":
        return FieldType.Date;
    case "Boolean":
        return FieldType.Boolean;
}

Could you please fix the issue?
