hentai.cafe extractor: prefer manga title of /hc.fyi/

[mo-han]

when set the "manga" metadata, prefer it in the manga page (with /hc.fyi/ in URL), to that in the chapter page
reason: some mangas have different title in manga page and in chapter page

example:
https://hentai.cafe/hc.fyi/1349
this page has title which starts with "[Distance] Devil Sisters!"
while in its chapter page (https://hentai.cafe/manga/read/devil_sisters/en/0/1/page/1), the title starts with "Devil Sisters!"

solution:
for such situations, extract "manga" metadata in /hc.fyi/ page if possible, and reuse it in chapter page

@mikf
hi, would you please add this patch?
don't know how to pass the CI checks, but since this change is very simple, could you add it into new version?
open to any suggestions or decisions

[mikf]

It is in the new version, it even says so in the CHANGELOG and release page.
Instead of merging your changes directly, I added commit 712c792, which also cleans up all issues I would have had with your PR.
Titles for /hc.fyi/ URLs now behave how you proposed they should:

$ gallery-dl https://hentai.cafe/hc.fyi/1349

/tmp/hentaicafe/[Distance] Devil Sisters!/c001_003.jpg
...
