Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

From a packaging view, v2.8.0 includes:

• a configuration option (solid harmonic ordering) is now runtime switchable, rather than library compile-time switchable, so a single 2.8 build can be used by more downstream packages.
• buildable for Windows

The actual scientific virtues of 2.8 can be seen here https://github.com/evaleev/libint/blob/v2.8.x/CHANGES

The particular builds introduced by this recipe contain higher derivative (i.e., gradient and Hessian) integrals and possibly some new types of integrals (e.g., f12). I've tried to make sure nothing was dropped, but if there is any trouble, please open an issue. See the NOTES file for exact generation configurations.

@matt-chan (horton) and @jan-janssen (votca), there's a new Libint out, v2.8.0, that's built here. If you've heard rumors of me changing up L2 with cmake, this isn't that. This is mostly user features, not build features. I've told the build to save artifacts if you want to try it out with your downstream packages. I won't merge before, say, 8am Thursday Eastern time. Please let me know if you want more time to test. Thanks!
