Make one-click executable for different platforms

[kuadrat]

First figure out which technology would be useful for this, then do it and make the executable available.

List of attempted solutions:

• pyInstaller: no luck when packaging pyqtgraph
• cx_Freeze: pyqtgraph works and runs with bugs. packaging piva gives an error related to importlib

pyInstaller seems like a good tool to use for this.

I will give it a try once I get around to it.

From my failed attempts I have come to the conclusion that pyInstaller and pyqtgraph don't go so well together...
