[celery] Sayonara Zetsubou Sensei S01

This release uses [re-timed and edited nonA subs](https://nyaa.si/view/1047104) muxed into the [1080p RAWs] that originally came from [here](https://nyaa.si/view/1431948). In addition, Bure karaoke added from [BTN’s release](https://nyaa.si/view/224510). Beyond that, I transcribed the text openings from [a.f.k.]'s release for episodes 1-3, 12. I also added some more translations to backboards in episode 3. Dialogue timing is still iffy in some parts, I fixed it where I found it wrong, but I focused heavily on sign timing and positioning, as well as making some style changes. I also attached the fonts, which the other releases did not do. Overall it's in better shape than it was before, but not perfect. I didn't do the karaoke for OP2. A lot of the work here is borrowed across a decade of fansubbers trying to get this series right, and I have added some to the pot. I added my own tag since the number of releases for this season is confusing. If you think you can contribute some more signs or timing fixes, by all means please do. I may do Zoku later... not sure for now. I'm a one-man shop that was just upset that 15 years have past since the show aired and I'm still watching shitty 400p AVI files because [a.f.k.]'s release is still most comprehensive subbing of the series.
