Document published CPTAC studies and those implemented in package

[sooheon]

Thanks for this great resource. I see devdocs has instructions on contributing datasets, it would be very helpful to see a roadmap of currently available CPTAC studies (looks like 58: https://cptac-data-portal.georgetown.edu) vs those implemented in this package.

This can help coordinate contributions as well as allow discoverability to those unfamiliar with CPTAC.

So the datasets to be included in the package are all the cptac datasets. You can see the ones currently available by doing a cptac.list_datasets(). As CPTAC generates more datasets, we put them into the package. right now, we have all the cptac datasets included.

also - the devdocs are mostly for internal developer use, instructions left for those who maintain the package.
