[DAR-5390][External] Add 'extract video-artifacts' command

[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 extract video-artifacts vommand that creates all artifacts and generates metadata file containing payload for registration.

DAR-5094 Create python script to generate video artifacts for read-only storage

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?

@AndriiKlymchuk Only issue is that ffmpeg@5 will be missing from the CI environment. Perhaps we can add a command here to install it?
