Minor Style Improvement

[thepigeonfighter]

With implicit generics it would make for more concise code if the public static methods for Success/Fail were moved up from Result<T> to Result.

The code would go from

Result<MyObject>.Success(obj);

to

Result.Success(obj);

Not a big change but this was a quality-of-life improvement for me so I thought I would share. I could make a pull request implementing this if desirable.
