Add support for importing BBH initial data generated by the SXS collaboration's open-source SpECTRE code.
@HengruiPrinceton and I have been evolving this data with AthenaK, with the idea to evolve high-mass-ratio and high-spin BBHs on GPUs. The SpECTRE code can generate non-conformally-flat, high-spin BBH initial data for this. It's excision data, so it is extrapolated into the excisions and then collapses into moving puncture gauge.
I'm working on a tutorial for generating and importing SpECTRE initial data, which I will link here once it's merged upstream in https://github.com/sxs-collaboration/spectre.
This is my first PR to AthenaK, so let me know if I missed something :)
