Germline: Allow to split some sequences in many files

IMGT considers some sequences as belonging to several germlines. This is the
case for example for TRAV../DV[45678] sequences that are shared by TRAV and
TRDV sequences. Therefore they should be put in both germlines.
Tests: Splitting TRV and TRA has consequences on -c germlines

Since some sequences are duplicated in two files, when indexing all germlines
with a single index, we have more ambiguous k-mers
Tests: Use -k 8 instead of -k 6

TRDD2 and TRDD3 can cope with -k 8 seeds.

Changes in the TRDV germline (inclusion of genes both in TRAV and TRDV)
induced false positives which prevented segmentation in one case with a too
small seed.

No need to be versionned anymore
germline.cpp: Increase delta_max for TRD+ recombinations.

Based on PAN data the delta_max can be much higher than what we previously set.
germline.cpp: keep the former names. Everything is TRG+
