New fixup function fixup_dc_ndl

Browse source 
Fixup the NDL value to '-1' at the very beginning of a dive.
Some dive computer report a NDL of 0 at the very beginning of a dive
and then only some 10 seconds later they report the correct value
like 240 min for the first time.
Translate this 0 at the beginning of a dive into our internal '-1'
for no info available.
