This PR introduces a new unfold operator to Flux, providing a functional approach for generating a sequence from an initial seed value. The unfold method offers a declarative alternative to the existing generate operator, inspired by similar functionality in Scala and Haskell.

The unfold operator enhances the API by allowing users to construct sequences in a functional style, which may be more familiar to developers coming from FP-centric languages. While functionally similar to generate, unfold focuses on a clean, declarative approach to defining recursive sequences.

Thanks for the proposal @asakaev. I can't say whether we'd like to integrate this, but it looks interesting as it's rather simple and encapsulates a familiar pattern. However, adding an operator opens up doors for more ideas. E.g. generate has 3 overloads. For unfold I can start to imagine someone with a desire for asynchronous variant the same way akka has. Consider the related discussion in #1974.
