Make a function that removes elements from the end of an array until the passed function returns true and returns the remaining elements in the array.

I am not sure thing can be made generic without it being an extension on Collection. Otherwise the call site sorta will have to look like this:

drop(arr: [1, 2, 3, 4, 5]) { element in
    guard let element = element as? Int else { return false }
    return element > 3
}

vs doing something cool like:

drop(arr: [1, 2, 3, 4, 5], while: {$0 > 3})
