Adding support for multisample VCF in postprocess-predictions

[Wai Yi Leung]

In the current code, there is an hardcoded output for the samplename: "default".

Whould it be an idea to change this to a name found in the bam "@RG SN=??". In my specific usecase I'm creating a multisample VCF (with merged events) and need a way to distinguish samples from each other.
