Integrate searchable schedule view

[hrw]

Since 2020 I am maintaining alternative view of FOSDEM schedule. With search and links to slides/attachements and videos. Current version is available at https://gpages.juszkiewicz.com.pl/fosdem-videos/ page.

Code is maintained in https://github.com/hrw/fosdem-videos/ git repository. Requires Python 3.6+ and should work on any OS.

I am fine with keeping and maintaining it where it is now but each year people ask me why it is not part of FOSDEM website.

@yoe asked me to open an issue to start discussion about moving it to FOSDEM infrastructure.

https://marcin.juszkiewicz.com.pl/test/schedule.html shows official page quickly switched to use DataTables.

Had to merge "Day" and "Start" columns to make sure sorting makes sense.
