If ENABLE_TBB, Intel's threading building blocks is downloaded and linked to all faunus targets. This enables the use of parallel std::execution policies currently available in GCC 9.1 and onwards. As exemplified in src/energy.h, a macro can be used to deternine if parallel execution is supported by the compiler. The linked TBB is a clone, currently of TBB 2020.2 with added CMake build, which enables simple download from our build system.
[ ] Anything else we want to add at this time? Many energy functions have been converted to parallel STL in this branch
