Add support for Swift Testing...

[woolie]

Is your feature request related to a problem? Please describe.
When using Swift Testing in Swift 6, trying to do an #expect(throws: XMLDeserializationError.***) {} fails to compile due to a requirement of Error types to be equatable using the #expect macro, which I assume is needed for enums with associated values (since I have not seem this problem crop us when I have used it without enum associated values).

Describe the solution you'd like
I'd like equatable to be added for the errors enums

Describe alternatives you've considered
For now I am commenting out my testing in those areas where I am expecting errors thrown.

Interesting... I haven't looked into Swift 6 compatibility yet, but there are some issues. It looks like SWXMLHash can build under Swift 6, but when I try to run the tests under it, those just crash.

I'll have to do some research into what will be needed for full Swift 6 support.

I've got a draft PR up at #283... branch is feat/swift-6-support. swift test is still failing for me, but I don't know if that is for a different reason. I think the #expects(throws: XMLDeserializationError.self) should work, though I'm not positive yet... I'm still working through getting the branch tested.

Feel free to give it a try to see if it works for you, though.

EDIT - swift test works for me now. My CI/CD script is still messed up, but that works. 🤞🏻 that it might work for you, too!

It doesn't work for me.

	@Test func shouldThrowWhenConvertingEmptyToNonOptional() async throws {
		#expect(throws: XMLDeserializationError.nodeHasNoValue) {
			try (parser!["root"]["empty"].value() as ComplexItem)
		}
	}

Still has an issue with the XMLDeserializationError.nodeHasNoValue not having an equatable conformance.

Nevermind, read the code woolie. It works fine with your changes.

That's great, thanks for verifying! I'll plan to merge and get a major version released with this once the latest Xcode is stable... I've got the builds mostly green, but they're inconsistent because of the Xcode betas I think.
