KeyError: 'authorModel'

It looks like the extractor is looking for the "authorModel" metadata, but Xhamster has changed the payload and no longer includes an authorModel containing the user info for the gallery. Checking the current window.initials value, it looks like some basic user info can be found in galleryPage.infoProps.authorInfoProps with the username itself at galleryPage.infoProps.authorInfoProps.authorName.
The user ID should be switched from:
"id" : text.parse_int(user["id"]),
to
"id" : text.parse_int(user["userID"]),
"url" is now at galleryPage.infoProps.authorInfoProps.authorLink
"name" is now at galleryPage.infoProps.authorInfoProps.authorName
"retired" may be gone entirely.
"verified" is now at galleryPage.infoProps.authorInfoProps.verified
"subscribers" value can be found at galleryPage.infoProps.subscribeButtonProps.subscribers

Also some slight modification to the pagination:
pgntn = data["pagination"]
could be changed to
pgntn = data["galleryPage"]["paginationProps"]

if pgntn["active"] == pgntn["maxPage"]:
should be changed to
if pgntn["currentPageNumber"] == pgntn["lastPageNumber"]:

the pagination next value also needs to be determined differently. Maybe just adding 1 to pgntn["currentPageNumber"]?

In testing out potential fixes I noticed some issues with missing verified and url values, due to contexts where the user account isn't verified and when the account has been disabled (but gallery itself is still active). Probably need more graceful handling of missing values instead of rejecting the download when the gallery still exists, but I'm not a Pythonista and my suggestions on how to do that wouldn't be worth much.
