MangaDex helpers

I got annoyed at the lack of search features in MangaDex, especially when trying to find something with lots of chapters for binge-reading so I went ahead and made this extension. Currently it only displays the highest chapter number for the manga in search page results (orange number before manga title). It uses Chapter Language Filter from MangaDex user settings to decide which languages chapters to count. Theoretically there may be some rare cases where it gives a wrong value but I haven't encountered any yet. Be aware that this only displays the highest chapter number for the selected languages, it does not count the amount of chapters, so for example if there is a manga with only one uploaded chapter but its chapter number is 96 then this extension displays the number 96.
