Read TSV from old and new QTM

[alexarje]

I have had some issues with reading TSVs generated from different QTM versions. Newer versions have a header line with TRAJECTORY_TYPES. There is also the option of having a line with column names. This is the set of header lines in the complete set:

NO_OF_FRAMES	
NO_OF_CAMERAS
NO_OF_MARKERS
FREQUENCY	
NO_OF_ANALOG	
ANALOG_FREQUENCY
DESCRIPTION
TIME_STAMP	
DATA_INCLUDED	
MARKER_NAMES	
TRAJECTORY_TYPES	
Frame	

But not all files have all of them. Have tried to add exceptions into the readTsv function, but struggle to make it work with some files. I also see that in QTM 2021 there is an extra tab at the end of the Frame line (a bug). Probably need to write in more exceptions to make it work for all sorts of files exported from QTM.
