Get iTunes grouping GRP1 tag #163

Hi, I'm trying to extract the "grouping" field from an mp3 file. getGrouping() returns null for my MP3 file; on examining it in a hex editor I find that the grouping field I want is stored in the GRP1 field. This seems to have been a change since iTunes v12.5.4.42 (see ITunes add a new Grouping field but Ignores the Existing one ! for more information).

Is there any chance of getting a new method added to this library that retrieves the grouping from the GRP1 tag?
