Update Travis-CI to use the new homebrew addon

 - This reduces the complexity of the CI infra and makes specifying dependencies easier
 - More testing on macOS should now be enabled using both:
   - Native CMake w/ Apple Clang and OpenMPI builds and
   - The projects Brewfile to build w/ GCC & MPICH
