Funcky 3.5.0 | Funcky.Async 1.4.0 | Funcky.Xunit 2.1.0 | Funcky.Analyzers 1.4.0

This update is mainly to update to .NET 9 but also has several smaller improvements.

.NET 9

Thanks to the new [OverloadResolutionPriority] attribute, we've been able finally fix
the ambiguous call errors when using DictionaryExtensions.GetValueOrNone:

Dictionary<string, string> favouriteFoods = new();
Option<int> tausFavouriteFood = favouriteFoods.GetValueOrNone("Tau");
//                                             ^^^^^^^^^^^^^^
// This used to produce a `error CS0121: The call is ambiguous between ...` error
// and now simply works 🎉

In good old fashion, we've also added new parse extensions:

• ParseExtensions.ParseAssemblyNameInfoOrNone
• ParseExtensions.ParseTypeNameOrNone

Policy for EOL Target Frameworks

We've explicitly written down our policy for how we deal
with older / EOL target frameworks.

In short: EOL target frameworks are supported by Funcky until the next major version.
However, we may no longer test Funcky against those target frameworks, so we
can't guarantee that everything works smoothly.

New APIs

In Funcky 3.0 we've changed CycleRange and RepeatRange to return an IBuffer
to enable us to memoize the collection, preventing unnecessary enumeration. This however
is unpractical for uses where you want to cycle an already materialized collection.
This release adds two new methods to accommodate that use case:
CycleMaterialized and RepeatMaterialized.

For convenient downcasting of Option<T>, Result<T> and Either<TLeft, T> values, we've added a new
DownCast class:

Option<object> option = Option.Some("hello world");
Option<string> downcasted = DownCast<string>.From(option);

Funcky.XUnit

Funcky.XUnit has been updated to the latest version (2.9.3) of xUnit.net.

Due to changes in xUnit we've had to change the exception type thrown by our FunctionalAssert methods
from AssertActualExpectedException to XunitException.

Funcky.Analyzers

The new analyzer rule λ1009 prevents you from accidentally default-instantiating
Either, Result and EitherOrBoth.

Funcky.Async

The PowerSet and WithPrevious extensions now correctly pass along the cancellation token.
