Parameterized attributes do not work!

[AlbatorLaho]

I've encountered some problems with parameterized attributes. (running MacOS 12, Monterey)

The Attribute enum for parameterized values are incorrect... they shouldn't end with Parameterized.

enum Attribute {
    case boundsForRangeParameterized = "AXBoundsForRangeParameterized"
    // should be:
    case boundsForRangeParameterized = "AXBoundsForRange"
}

Personally, I would also like the parameterized attributes to be separated into another enum. ~~I'm not sure why they're in the same enum in the first place... they're never interchangeable are they?~~ I realize it's probably for simplicity of functions like attributeIsSupported... but I'd still think it makes sense for them to be separated.

The other thing I found is that the parameterizedAttribute in UIElement doesn't work correctly. I was trying to set AXBoundsForRange and passing in a CFRange, but it would throw an AXError.IllegalArgument error. I figured out that it's because the param value does not use packAXValue, unlike setAttribute.

open func parameterizedAttribute<T, U>(_ attribute: String, param: U) throws -> T? {
    ...
    let error = AXUIElementCopyParameterizedAttributeValue(
        element, attribute as CFString, param as AnyObject, &value
    )
    // should be something like this:
    let error = AXUIElementCopyParameterizedAttributeValue(
        element, attribute as CFString, packAXValue(param), &value
    )
    ...
}

I can't easily test this fully, since I can't access packAXValue in an extension (because it's fileprivate), but doing manual conversion to an AXValue seems to fix it!

I also encountered this problem.

Confirm that a6bd34f8cd30980a1e5fbf8bec41b77068f787ee and 8d8b307edeb76ef133784d8be3981824c3c5fefa can fix it.

@tisfeng Yes, those appear to fix the issue(s)!
