Cannot create a `SymbolicSparseRowMat` with `SymbolicSparseRowMat::new_checked()`

[ThomAub]

Describe the bug

Cannot create a SymbolicSparseRowMat with SymbolicSparseRowMat::new_checked() or new_unsorted_checked()

*To Reproduce**

pip install numpy scipy 

import numpy as np
import scipy.sparse

(nrows, ncols) = (4, 10)

random_matrix = scipy.sparse.random(num_rows, num_cols, density=0.2, format='csr', dtype=np.float64)

# print(f"CSR data array (values): {random_matrix.data}")
print(f"{nrows=} {ncols=}")
print(f"CSR indptr array (row_ptrs): vec!{random_matrix.indptr}")
print(f"CSR indices array  (indices): vec!{random_matrix.indices}")

// src/sparse/csr/symbolic_own.rs
#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn symbolic_sparse_row_mat_new_checked() {
        let nrows = 4;
        let ncols = 10;
        let row_ptrs = vec![0_u32, 4, 6, 6, 8];
        let col_indices = vec![0_u32, 1, 3, 5, 0, 3, 4, 5];
        let new_checked =
            SymbolicSparseRowMat::new_checked(nrows, ncols, row_ptrs, None, col_indices);
    }
    assert_eq!(new_checked.nrows, 4);
}
