[Exhentai] the original image is no longer being downloaded, only the low res image is

Exhentai has changed the URL of all original images for Firefox users which is the browser that the default user-agent is using, this causes it to only download the low res images.

• We now do an URL rewrite for fullimg requests to fix an issue specific to Firefox where files were sometimes being saved as "fullimg.php"

The reason original images no longer download is because the URL for original images was changed. It isn't specific to Firefox users or a specific User-Agent.

The original image URL no longer includes fullimg.php which is what gallery-dl looks for to determine if there are orignal images to download. The new original image URL looks like: https://exhentai.org/fullimg/<gallery_id>/<page>/<image_token>/001.jpg.

Replacing the instances of fullimg.php with fullimg in gallery_dl/extractor/exhentai.py allows for original images to be downloaded again when I run gallery-dl from source in my local repo.
