Add writing interoperability tests

[jamesmudd]

What is the suggestion?

Currently writing tests write a HDF5 file and then read it back with jHDF to verify the contents. In addition it would be good to confirm the file can be read correctly by the HDF5 C library. Suggested here https://github.com/jamesmudd/jhdf/issues/354#issuecomment-1902251615

How would it be an improvement?

Verify interoperability as more writing support is added.

Additional context

Best approach so far I think is to use h5dump to output XML then parse that in the JUnit test to verify
