RNA-seq Strand Specificity Metric

Add strand specificity to the Picard RNA-seq metrics including a PP param for RNA-seq models.  This PR will require a backfill of RNA-seq processing profiles to a value of 'NONE' to match Picard's default value.  Also existing software results will require a new lookup hash.  Tagging @dufeiyu as we have already discussed this via email.
I will go through and fix these.
