[Format][C++] Add CSF sparse tensor support #20806
Description
Perhaps in the future, if zero-copy and future-proof-ness is really what we want, we might want to add the CSF (compressed sparse fiber) format, a generalisation of CSR/CSC. I'm currently working on adding it to PyData/Sparse, and I plan to make it the preferred format (COO will still be around though).
