[FEATURE] When generating video/audio service files, copy a reference to the transcript files.

[rosiel]

Overview of feature request

When you upload a video/audio file, a service file derivative (can be) generated. These lack the transcripts that may have been uploaded in the "Media Track" fields (an Islandora-provided field type). I propose that we copy them from the Original File to the derivative. Not copy the file, necessarily, but make another reference to the same file.

What kind of user is the feature intended for?

End users (so they can see transcripts)
Content managers (easier workload)

What inspired the request?

Reading through PREMIS Data Dictionary, which suggested the same thing.

What existing behavior do you want changed?

Any brand new behavior do you want to add to Islandora?

as mentioned, add a link to the existing transcript/track files.

Any related open or closed issues to this feature request?

Just had the think: Wondering if another level of indirection might be useful, to have transcripts exist on a separate media (which might be referenced from the various places to which it applies on the original and service files and so on), to avoid duplicating the references to the file(s) in multiple places in each instance?
