Make the Content Filter setting non-synced (again)

[A_Walking_Meme]

i never understood why it was changed to be synced.
the last thing i need when i'm using mangadex on a bus is ACTUAL PORN.
if i really wanted to see something like that on another device i can easily turn it on again, ON THAT DEVICE.
no matter how much i think about it i don't understand why the Content Filter cant be different for each device.
