rescheming 2: electric pakalu

[hecko-yes]

changes:

• original-title and original-authors are now subfields of original (potentially allowing for expansion if desired?)
  • i put it under tags, imagining it as the last entry in a series of "what is the work" followed by "how to get it"; putting it under license might've made as much sense but ¯_(ツ)_/¯
• all optionals and nullishes have been replaced with nullables, aka every field must be explicitly nulled and can't simply be absent (i still don't like it much but it's what the sturgeon ordered)
  • as a side effect of how i did it it also sorts everything in accordance with the schema which i do like :3

same wrapper code as in #36

inner code used (cc0)
