Difference of RollingWindowSplitter and StatisticalChunker

[sopheck]

Hi,
first of all, thank you very much for your work, which is helping me a lot. ❤️

I have a question about the chunkers or splitters that I have not been able to answer. You have moved the chunkers from semantic_routers to semantic_chunkers, but the RollingWindowSplitter still exists in semantic_routers. What is the reason for this? It looks very similar to the StatisticalChunker. What is the difference? And which of the two should I use for texts?

Thank you!
