Transform the qobj to CSR only if it is Dense, in case more data types are introduced in the future.

Could we add a small test for this? E.g. check that a Dense operator really is expanded to a CSR? Otherwise looks good.

Thanks for adding the test.

Why were the qiskit tests removed?

Deleting qiskit_test was a mistake

And maybe I should make the same change to the function in qutip-v5 .

I would say yes. Ideally the two functions should remain the same.

@Ericgig Does the change look good to you? I'll make the same PR to the main qutip

I am fine with setting csr as the default type to expand_operator.
