Encode enum cases without associated values

[Amzd]

Fixes #157

This breaks some @IgnoreCodingInitialized tests but that API is too confusing for me. I have no idea what it is actually supposed to do, so I can't tell if the failing tests are actually breaking the intended use. A maintainer needs to look at that.

Can you provide what is the error you getting? The change seems to be in the right direction. So the tests might need to be updated with latest data.

I think this will cause unused variable warnings in case of your original example. Can you address that in someway? May be passing some flag to this preSyntax closure and customizing the output based on this flag?

[Amzd]

I changed nothing in the decoding part and there there is also an unused variable so this seems like skewed standards but I have fixed this.

@Codable
@IgnoreCodingInitialized
enum SomeEnum {
    case bool(_ variableBool: Bool = true)
}

this previously encoded to nothing which means now all the tests fail with diff:

 extension SomeEnum: Encodable {
     func encode(to encoder: any Encoder) throws {
         var container = encoder.container(keyedBy: CodingKeys.self)
         switch self {
         case .bool(_: _):
+            let _ = container.superEncoder(forKey: CodingKeys.bool)
-            break

and it is unclear to me whether this is expected behavior from @IgnoreCodingInitialized or if the tests were just wrong.

I believe the previous behavior of @IgnoreCodingInitialized was a bug as I think on enums it is only meant to ignore the associated values, not the whole value. This PR fixes the bug but this might break implementations relying on that bug as they may have misinterpreted @IgnoreCodingInitialized to mean "ignore encoding completely". Thoughts are appreciated, if you say the fix is fine then I update the old tests.
