Bug(?) - allow no additional segments in consent

[mekline]

While trying to update the video-consent plugin I tried removing the additional_segments parameter and got the following error:

Uncaught (in promise) Error: You must specify a value for the "additional_segments" parameter in the "consent-video" plugin.

It would be more natural for the plugin to allow this to be null, and not require the user to input additional_segments: [{}] (which fixes this bug)

(Only tried this on video-consent, consent_005, English, same issue may be present in other versions)
