[req] bound_claims notation allowing for the "and"ing of claims from a list

[xojc]

If a JWT has the following claim:

{
  "foo": ["c", "d"]
}

it will match on a bound_claims value of

{
  "foo": ["a", "b", "c"]
}

since that rule indicates that the bound_claims match on a list "foo" containing either "a" or "b" or "c".

I would like to see a feature in which a bound_claims map can be written to specify that the list "foo" must contain more than one specific value, e.g. "c" and "d".
