Read pnsSet.xml files

[ephathaway]

We would like to add functionality to read pnsSet.xml files. These files are generated when recording with the Physio16 kit and contain info about the sensors included. This file is very similar to sensorLayout.xml, so we could potentially create a superclass in mffpy/bin_files.py that encompasses all "sensor files" and then create subclasses for SensorLayout and PNSSet.

@ephathaway , is this still something we need to do? Can you add some "pnsSet.xml" example here?

[ephathaway]

@jusjusjus, yes this is fairly high priority for me anyway because it will support what I am doing with MFF reading in MNE. Being able to parse pnsSet.xml gives us the names of the PNS channels (ECG, EMG, etc.). Otherwise we have to guess what they are or just give them generic names.
