Show units for the parameters

[erlendviggen]

As of release 0.2.6, dlisio lets us access the units of parameters. This will allow us to correct a deficiency of the acoustic log data notebook, where we were not previously able to find the units of the parameters that we list in the notebook and had to refer to other sources.

Once dlisio gets a more final interface for parameter units, I can implement getting the units into the notebook.
