[BUG] StorySeedling - Jumbled/empty text on passages

[noaione]

For tracking purpose, they change some stuff around so text might become jumbled messes or will return error.

Please report any additional issues here.

Latest extension version: 2.1.7

Some discoveries:

• Text are ROT13 Text are shifted codepoint
  • Rendered using custom font based on Inter (already violates SIL OFL they've renamed it to Vagre so it doesn't violate the license anymore)
• Contains "Copyrighted material" text (lol, lmao even)
• Contains padding text which is hidden when rendered in HTML
• Request need to send captcha if needed and nonce
  • They introduce CF turnstile/captcha when reading (this is on top of standard CF security check)
  • This one is a bit annoying, I wish there is a webview button on chapter :(

New issue:

• Some line got some of their spaces removed after punctuation, I'm guessing this is because the bad way I'm handling the ROT13

New issue (also fixed):

• They change from ROT13 to adding 12027 for lowercase and 12033 for uppercase. A bit harder to solve in lua since they don't have native utf8 support until Lua5.4 I think?
• Some text are not corrected, this is because my text handling which should be fixed by 2.1.7
