ntRoot v1.1.3

• Release v1.1.3
• Added flexibility for parsing input VCFs when using --custom_vcf
  • Accepts 8-10 columns, auto-detects for parsing bedtools intersect file
    • Previously, required 10 columns (as were present in all VCFs tested), but it is valid to have as few as 8 (as there are 8 required columns as per VCF specifications)
  • If there are more than 10 columns, this would indicate a multi-sample VCF, which doesn't make a lot of sense for using ntRoot to evaluate an individual's ancestry - in this case, an informative error message is printed
