Binary Fuse filters as an alternative to BIP 158 GCS

The current implementation of Fuse filters has encountered a specific issue where 55 blocks are being skipped. This is due to unresolved issues with tiny-filter corner cases which have not yet been addressed in the algorithm. It is unclear whether these problems arise directly from failures in the construction algorithm or if there is a need to re-seed the entire process to accommodate these exceptions. Further clarification and detailed investigation into these corner cases are essential to enhance the functionality and reliability of the Fuse filters, ensuring that all blocks are processed efficiently without the need to skip any. Understanding the nature of these corner cases will also help in developing a more robust algorithm that can handle such scenarios effectively.
