Add fluent date

[mariusz-schimke]

I was wondering if you would accept the following changes. My intention is to let specify dates by typing a month name next to an integer year like this: 2022.Apr(19), with a possibility to express time as well: 2022.Apr(19).At(22, 50). I thought I could propose these changes to you as they apparently seem to fit to your library, but I will understand if you don't agree ;). I just thought it would make no sense to create a separate NuGet package for this.

Thanks!

I forgot to mention the intention behind this implementation. It's for those situations where you provide a date statically, and it stays in the code base. W use that for automating database migrations creation using Nuke Build. I thought it would be more readable than new DateTime(2022, 4, 20) or Date.Parse("2022-04-20") or so, but its a matter of individual preferences. It could possibly be used in unit tests as well.
