Problem Description

Usually timestamps are formatted like this in seconds https://youtu.be/0IxaD8QwKTs?t=98s

But turns out that this human readable format (Hours:Minutes:Seconds) also works in Youtube, but not yet in freetube

Proposed Solution

Be able to load based on the alternative timestamp format
