Python CLI: slightly beautify event printing
Pythong CLI: allow readout of raw events. Are returned via Python
interface just as vector of integers for now.
Python CLI: add daqGetRawEvent to test new HAL readout functions.
Working towards solving #202
Possible solution to #202 - needs more testing with a multi-channel
DAQ (module) and/or artificially injected data blobs.
HAL: remove some debugging output.
Another attempt for solving #202: mixed up some pointer assignment
this lead to a double free. We were not copying out the events from
the pipe but juts referencing the same memory over and over.
