Hi @willow-ahrens @hameerabbasi,

This PR adds compat changes to make finch backend compatible with Scipy, sklearn, etc., by adding:

SparseArray marker class that is already used by PyData backend and SciPy, to identify a pydata/sparse object.
Tensor.from_scipy_sparse() to convert Finch tensor to SciPy object.
Tensor.to_scipy_sparse() to convert SciPy object back to Finch tensor.

SciPy PR: https://github.com/scipy/scipy/pull/19796

The PR is ready from my side!
