Add VEP annotations to the somatic SNVs

[NagaComBio]

Feature Requirements:

• Add VEP annotations to the SNV calls.
• Parse transcripts with "HIGH" or "MODERATE" VEP consequences impact from the INFO column and add them to a new column with Gene, Consequences, Exon/Intron counts, HGVSc and HGVSp information.
• Still to be decided:
  • Should this be done for all variants?
  • Should the VEP annotation be removed from the INFO column once it is parsed?
