I have expanded on the functionality to cover more use cases

I think we need to support combinations of the following.

"cookies allowed": {"marketing":1,"performance":0}

"cookies allowed": {"marketing","performance"}

"cookies allowed": "all"

"cookies allowed": {"all"}

We should also probably support the inverse too for opt out scenarios.

"cookies rejected": {"marketing":1,"performance":0}

"cookies rejected": {"marketing","performance"}

"cookies rejected": "all"

"cookies rejected": {"all"}

A lot of the cookie modules we have tried seem to work differently but all have a combination of cookie groups stored in an array (with or without a true/false flag).
