Unstructured write bug fix, rectilinear read bug fix
Fix for two bugs.
- The DataSetWriter was saving the coordinates array as a field. When the dataset was read back in, the coordinates would be read twice resulting in a crash in adios. This was fixed for both the Fides_Data_Model schema and fides/schema.
- It's possible to have rectilinear coordinates and unstructured cell sets. Fixed the logic to check for structured/unstructured cell set and then the coordinates.
