Description

I note that the function "read_v3_10x_h5" regards user's input as csr_matrix by defsult. However, there are various sparse storage formats such as COO and CSC. I think it would be better to add some checking and support more storage formats like COO and CSC.

Research direction

Start in scanpy/readwrite.py at the read_v3_10x_h5 function and inspect how sparse input is currently treated as csr_matrix. Define the supported sparse storage formats and add format checking or support for COO and CSC, then verify that the function handles those formats as intended.
