Version 1.6.0#

This release adds support for UHI serialization for use with the uhi library, supported in the next release of uhi. A new diagnostic test has been added in the wheel, so you can quickly check your compile of boost-histogram without the full test suite. Quite a few fixes are present, as well, including a fix for *=, setting a range with a scalar, setting with a callable in a slice. Backend changes include many new clang-tidy checks that reduce the number of copies and refcount changes. We now build with pybind11 3.0.

This release drops support for Python 3.8, and adds Python 3.14(t), iOS, Windows ARM, and GraalPy.
