Use a non-default dxplid to collectively write datasets and metada datasets. #42

Previously we were not able to use a non-default dxplid because of an issue related to lib state calls.

PR #41 fixed this issue so now we can use a non-default dxplid and setup collective MPIIO to write the datasets.
