[mangadex] pornographic titles return no results anymore

[nexen-eve]

I noticed the last few days pornographic titles return no results anymore.

For example:
gallery-dl --verbose --ignore-config https://mangadex.org/title/584ef094-b2ab-40ce-962c-bce341fb9d10
or
gallery-dl --verbose --ignore-config --username xxx --password xxx https://mangadex.org/title/584ef094-b2ab-40ce-962c-bce341fb9d10
or
gallery-dl --verbose --ignore-config --username xxx --password xxx --cookies cookies-mangadex-org.txt https://mangadex.org/title/584ef094-b2ab-40ce-962c-bce341fb9d10

Returns:

Downloading a specific chapter still works.

Adding contentRating[]=safe&contentRating[]=suggestive&contentRating[]=erotica&contentRating[]=pornographic to the get request might solve this.

Can confirm adding
"contentRating[]" : ["safe","suggestive","erotica","pornographic"]
after line 214 in mangadex.py seems to ensure all content ratings are requested and everything works as intended again.
