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)
20.06.19 : 0.5 : extended CSV output to 12 columns by adding column 'MRP' (morphological segmentation)
                 extended emuR output to BPF tiers KSS and MRP; in contrast to CSV output both KAN and KSS 
                 are output, if both are present in input.
                 extended TextGrid output to BPF tiers KSS and MRP; in contrast to CSV output both KAN and KSS
                 are output, if both are present in input.
