when value has more than seven decimal places,c# no number in eighth digit will be recorded.
here is an example:

when it converts to Timespan, his TotalSeconds will be 130.0400000
so it will cause the ThumbnailURL and PreviewURL to be wrong url


https://trace.moe/thumbnail.php?anilist_id=269&file=234.mp4&t=130.04&token=uynf7OyzeOhda9dbMPMpvinZJPk
the correct url should be https://trace.moe/thumbnail.php?anilist_id=269&file=234.mp4&t=130.04000000000002&token=uynf7OyzeOhda9dbMPMpvinZJPk
so I think the type of FoundTimestamp should be changed to string or double, and another function should be written to get TimeSpan
