Script for processing a video and generating SECTIONED_V2 artifacts for read-only item registration

[AndriiKlymchuk]

Problem

For read only registration of videos in SECTIONED_V2 format clients need to prepare all processing artifacts them-self.
It is very complicated as requires to perform a lot of steps.

Solution

Develop script that creates all artifacts and generates metadata file that contains payload for registration as well as storage keys mapping to upload files.

We plan to send this script to J&J and later make it part of darwin py with proper code organization and test coverage.

This PR doesn't have to be merged, but rather reviewed and closed in favor of proper implementation as part of darwin py that will be done later

Looks good, and works well when I test it. To get into the repo I think we should consider:

• Allowing the script to process multiple videos from a single command, perhaps it could work on a directory of files
• Adding an explicit warning / documentation stating that this may become out of sync with our backend video processing pipeline
• Placing it in a new darwin/scripts directory or similar, as no scripts of this type exist in darwin-py currently

Agree. Also we need to cover it by tests.
I also sync maybe it shouldn't be a separate script, but rather part of darwin py cli?
