Third instance of the same shape as the DSF and DSDIFF changes:
static_cast<int>(static_cast<double>(duration) / 10000.0
- static_cast<double>(preroll) + 0.5)
duration and preroll are both long long values read from the file
properties object, so the result can land outside int, and converting a
double the destination type cannot represent is undefined:
taglib/asf/asffile.cpp:240:22: runtime error: -2.80375e+14 is outside
the range of representable values of type 'int'
Only skip the conversion when the value will not fit. Values that do
fit, negative ones included, are set exactly as before, so the three
.wma files in tests/data still report lengthMs 3549, 96502 and 3712.
Found by the same fuzzing that turned up the DSF case.
