Version 2.8.0

Summary

• Improvements to TFormula support
• Significant improvements in platform and python version support, including freethreaded python 3.14
• ⚠️ flat awkward arrays are now returned from high-level evaluate() calls when flat awkward arrays are passed in, see #296
  • Previously, the output would be a numpy array. If that is required, one can call .to_numpy() on the output
