18.05.19 : 0.2 : first version
07.06.19 : 0.3 : removed OUTFORMAT=emuDB, since the tool does not really create an Emu DB, just 
                 a Emu DB *_annot.json file.
13.06.19 : 0.4 : added TRN output to CSV converter, even if the input BPF contains no proper hierarchy.
                 that enables conversion of Pause Detection output (TRN only)
