Pull mutation data from GDC

[ielis]

The PR creates GdcMutationService to retrieve variants of CDA subjects from GDC.

See the test for example usage.

The logic is based on the gist written by @sujaypatil96 here.

There are still some TODOs left. The mapping of the VCF coordinates and functional annotations should be complete, however, we still may need to explore GDC to add the read depths, gene, and the mutation status.

When ready, we can use GdcMutationService e.g. within CdaTableImporter, to get the variants for the subjects.

Were you able to resolve the above issue you were running into @justaddcoffee?

[justaddcoffee]

@sujaypatil96 yes, this problem went away. Possibly it was a problem with a stale cache file, b/c it went away when I deleted the old cache .pkl files

@sujaypatil96 @ielis btw, can we merge this PR?

[sujaypatil96]

Awesome!! this PR is ready to be merged then 🚀
