Length infered for dynamic length fields sometimes is wrong

[skleber]

The maximum field length infered for dynamic fields by
netzob.Inference.Vocabulary.FormatOperations.FieldSplitAligned.FieldSplitAligned.FieldSplitAligned#_mergeAlign
into the tuple (entryVal, entryDyn) from variable splited in line 252 of
FieldSplitAligned.py
is not correct for "some" inferences like:

<class 'ScapyDissector_ntp.NTPi_Symbol2'>
fieldlengths netzob from domain
[8, 8, 8, 16, 8, 24, 8, 8, 16, 224, 80]
408
fieldlengths netzob counted in value
[8, 8, 8, 16, 8, 24, 0, 8, 16, 224, 64]
384

The values at the bottom are correct, i. e. 64 instead of 80.

I will provide some minimum working example to verify in the near future.
