Support long datatype in writing hdf5 file

[lizhang386b]

First of all thank you @jamesmudd for creating this project. It makes java programming a lot easier to create/read hdf5 files.
It seems long datatype is not supported yet in writing. Any plan on when this feature will be added and released?

[jamesmudd]

Thanks for your interest in jHDF. Your right writing long dataset is not yet supported. This will be added in the next release hopefully not too long away, just want to clean up the code for writing attributes.

Should be working now in v0.8.0 let me know. Thanks

Confirmed 0.8.0 works with long type in writing HDF5.
Thank you very much for the fast release. Appreciate it.
