Video hashing is broken/identical for almost all files

[prof79]

Bug Description

Almost all videos hash the same.

Expected behavior

Videos should hash differently in general but identical videos downloaded by old and new M3U8 processing should hash the same.

Actual behavior

Almost all videos hash the same.

Environment Information

• Operating System: all
• Fansly Downloader Version: v0.8.0-v0.8.1
• Fansly Downloader Type: all
• Specific creators name: all
• Preliminary fix in: v0.8.2

Impact

More graving than thought at first glance. Will prevent downloading of new videos.

Additional context

Excluding the mdat box as a whole was a silly move under time pressure.
Getting hold of ISO MPEG-4 Part 12 and 14 standards would be very helpful.

Partially, the most graving part at least, is fixed with https://github.com/prof79/fansly-downloader-ng/releases/tag/v0.8.2 . Duplicates may happen between v0.7.* and v0.8.2 and are tracked in a new issue under #13.
