Updates due dependency version changes. (#1960)

* Updates due dependency version changes.

h5py recently changes and now values once returned as str are now returned as bytes.
This would have caused a much larger change, so instead the version is restricted to <3.0.0.

This caused the bulk of the testing failues.
A few other changes were needed to make a few other tests pass.
