Create a test suite for the GAMBLR functionality

[Kdreval]

This update to the GAMBLR dependency GAMBLR.data provides the sample metadata and maf, seg, and bedpe data. The data is provided in both projections. This will now allow the development of the test suite that will ensure GAMBLR consistency and functionality throughout updates.
This should supersede the test_functions.R and test_remote.R and should make the functionality testing automatic on each PR.
