Purple failing with latest merged somatic call set

Purple is failing when provided the latest merged somatic call set with the SEQC TN pair. It errors out while parsing the input somatic VCF file with java type-casting errors.

Here is a screen shot of the error:

At some point the program fail when try to type cast a list to a string.

To resolve the issue:

1. Build a docker image with the latest version of hmtools dependencies for sage (needs latest version of java, needs R, and circos)
2. Update to the latest jar file for hmftools purple (v4.0.2)
3. Pass purple SAGE's filtered norm vcf file (purple does not like the latest merged VCF from multiple callers)
4. Use the latest v6_0 resource bundle from hmftools: https://console.cloud.google.com/storage/browser/hmf-public/HMFtools-Resources/dna_pipeline/
