Complete HDF5 compatibility

[wiheto]

Some networkmeasures will not run if TemporalNetwork is in the HDF5 format. These should be fixed.

Measures are:

temporal_degree_centrality, volatility, fluctuability, sid, topological overlap, and participation coefficient with negative edges)

Edit: After this is done, some benchmarking for speed should be done. Some of the upcoming trajectory stuff is snailspeed in HDF5

Dropped from 0.5 and won't be until 0.6 as speed issues are caused by HDF5 implementation and I need to read up more about this.
