Is it possible to add Bulk UNdying?

[ffuentesm]

I love the ability to bulk dye items, which makes it an easier and cost-effective method to get a stack of a certain color.
I was just wondering if it was possible to add an "un-dying" method using the washer.

Most un-dyeing methods are implemented through the cauldron instead of crafting recipe, which make is it quite complicated to test arbitrary dyed items.

A possible workaround would be reverse searching dyeing recipe base on the result, but that would risk including arbitrary fake dyeing recipes (like the dough to slime ball one), filtering out those would require a precondition to test if the ingredient is in c:dyed tag, which would avoid fake dyeing recipes, but would also miss those mods who forget to add to the c tag.

Will look into this ;)

Perhaps use a tag for items to test with the cauldron? i.e. only have #minecraft:dyeable and #c:shulker_boxes in it by default.

EDIT: I suppose #minecraft:banners would also be included.
