some durations == -1

In the task f0ContourFeatureFileMaker, at this line:

gradle-marytts-voicebuilding-plugin/src/main/groovy/de/dfki/mary/voicebuilding/tasks/F0ContourFeatureFileMaker.groovy

Line 273 in 9f641d5

long tsSylEnd = units.getUnit(syl.getLastUnitIndex()).startTime + units.getUnit(syl.getLastUnitIndex()).duration;

the duration of the unit == -1 which leads to fails the following assert

@psibre is there a reason for this:

gradle-marytts-voicebuilding-plugin/src/main/groovy/de/dfki/mary/voicebuilding/tasks/PhoneUnitFileMaker.groovy

Lines 57 to 59 in 9f641d5

	out.writeLong(utteranceEndSample + unitStartSample)
	out.writeInt(-1)
	numUnits++

The Timeline format marks the boundary units as having duration -1; IIRC there are even some parts in the code where this antipattern is used to check if a unit is a boundary. =(
