Get the actual data of a sensor bad pixels map. Caller must provide pre-allocated arrays: out_component_indices: num_component_indices entries (may be NULL if num_component_indices == 0) out_bad_rows: num_bad_rows entries (may be NULL if num_bad_rows == 0) out_bad_columns: num_bad_columns entries (may be NULL if num_bad_columns == 0) out_bad_pixels: num_bad_pixels entries (may be NULL if num_bad_pixels == 0)
