Update CTNNB1 protein changes in crc_msk_2017

[rmadupuri]

What?

Fixes #1836

1. Recurated the MAF from Table S3. The mutations file in datahub master lists ~14k somatic variants where as the paper shows ~18k variants.
2. Reannotated the MAF with GN. That fixed the protein change of the CTNNB1 intragenic in-frame deletions as below
