Severus v1.2

With version 1.2:

• Severus now supports PoN input for tumor-only runs. We provide PoN data for GRCh38 and chm13

• Improvements in the failed SV filtering

• Improved single BND detection

• New parameter added: --max-unmapped-seq to define the maximum unmapped sequence between two mapped sequences (length of sequence reported in INSSEQ in the vcf)

• Updates in vcf format:

1. INV and DEL are now restricted to the reciprocal inversions and true deletions with decreased coverage. The rest are represented as BNDs. For reciprocal inversions, instead of representing it with two rows (4 BPs), we will represent it with a single row (2 BPs).

2. Minor fixes in vcf formating.
