Review sub-categories

Hello, I would like the API to be able to call review sub-categories.  

Adding support for this. Confirming the data exists in OwnerRez but isn't exposed via the API — the Reviews spreadsheet export includes CleanlinessStars, CommunicationStars, AccuracyStars, CheckinStars, LocationStars, ValueStars (plus Booking.com-specific fields) and a Private Feedback column, while GET /v2/reviews returns only overall stars, body, and response. Would like to see both the sub-category scores and private feedback added to the API response. Private feedback in particular contains actionable guest requests that are invisible to any automated analysis today.

Also jumping in to support this one - we have a workaround but it's fragile because it's based on parsing the review posted email.
