array-fold kons knil arrayprocedure

If we use the defining relations for fold over lists from SRFI 1:

(fold kons knil lis)
    = (fold kons (kons (car lis) knil) (cdr lis))
(fold kons knil '())
    = knil

then (array-fold kons knil array) returns

(fold kons knil (array->list array))

It is an error if array is not an array, or if kons is not a procedure.
