ntEdit v1.3.4

support for IUPAC characters in snv (-s 1) mode

Better handling of IUPAC nucleotide codes in SNV mode; In that mode, IUPAC positions will be inspected for A,C,G & T (no just the base(s) not captured already by the IUPAC code as it is the case in polishing mode.

no degradation of performance, except for additional computing needed to inspect possible alternate base substitutions to IUPAC codes in SNV -s 1 mode
