Add a "displayNameKey" to the IEnumMember interface #75
Description
Within powerbi-visuals-utils-formattingmodel, the ItemDropdown slicer utilizes the IEnumMember interface within the definitions.ts file for its dropdown items and value. However, there is no way to have these dropdown items to be translated into other languages. If there is a way to have the IEnumMember have not only a displayNameKey associated with the interface but the ability to translate said key would be much appreciated.
