Magnus Jedvert d65e143801 Update video_quality_analysis to align videos instead of using barcodes
This CL is a follow-up to the previous CL
https://webrtc-review.googlesource.com/c/src/+/94773 that added generic
logic for aligning videos. This will allow us to easily extend
video_quality_analysis with new sophisticated video quality metrics.
Also, we can use any kind of video that does not necessarily need to
contain bar codes. Removing the need to decode barcodes also leads to a
big speedup for the tests.
