Return numeric_val as well as cn_state

[pintoa1-mskcc]

Oncokb CNA annotator can now accept numeric values that match GISTIC

Given that, can we report the numeric values in our final outputs as well? For reference:

For each gene-sample combination, a copy number level is specified:

"-2" is a deep loss, possibly a homozygous deletion "-1" is a single-copy loss (heterozygous deletion) "0" is diploid "1" indicates a low-level gain "2" is a high-level amplification.
