Leon Anavi bc6b98c7ce python3-nanobind: Upgrade 3.0.0 -> 3.1.0
Upgrade to release 3.1.0:

- Python subclasses can now combine one nanobind base with
  additional :ref:`Python mixins <python_mixins>`, including
  cooperative super() calls on CPython and PyPy. Inheriting from
  multiple nanobind bases remains unsupported.
- The low-level instance API gained
  :cpp:func:`nb::inst_python_derived() <inst_python_derived>`,
  which reports whether a nanobind instance belongs to a
  Python subclass of the bound type.
- Added new low-level functions :cpp:func:`nb::keep_alive_obj()
  <keep_alive_obj>` and :cpp:func:`nb::keep_alive_cb()
  <keep_alive_cb>`, which expose the mechanism behind the
  :cpp:class:`nb::keep_alive <keep_alive>` annotation.
- The new function :cpp:func:`intrusive_counter::ref_count()`
  returns the reference count of an intrusively reference-counted
  object while it is owned by C++.
- Fixed stale trampoline override caches on PyPy. Changing an
  attribute of a nanobind type now correctly invalidates the caches
  of its Python subclasses.
- The std::map/std::unordered_map and std::set type casters can now
  also handle containers like std::flat_map whose iterators return
  temporary values.
- The :ref:`Bazel documentation <bazel>` was rewritten and now
  presents an approach based on the Bazel Central Registry.
- Miscellaneous minor improvements.
