Subject: [PATCH] feat: Add Unspecified_Image option to Transfer enum in Video
 class.

The Transfer enum was missing value 2, which according to ITU-T H.Sup19 standards represents "Unspecified (Image
  characteristics are unknown or are determined by the application)". This value is often used for still image coding systems.
