Bumps pybind11 from 2.7.1 to 2.8.1.

Release notes

Sourced from pybind11's releases.

Version 2.8.1

v2.8.1 (Oct 27, 2021)

Changes and additions:

• The simple namespace creation shortcut added in 2.8.0 was deprecated due to usage of CPython internal API, and will be removed soon. Use py::module_::import("types").attr("SimpleNamespace"). #3374
• Add C++ Exception type to throw and catch AttributeError. Useful for defining custom __setattr__ and __getattr__ methods. #3387

Fixes:

• Fixed the potential for dangling references when using properties with std::optional types. #3376
• Modernize usage of PyCodeObject on Python 3.9+ (moving toward support for Python 3.11a1) #3368
• A long-standing bug in eigen.h was fixed (originally PR #3343). The bug was unmasked by newly added static_assert's in the Eigen 3.4.0 release. #3352
• Support multiple raw inclusion of CMake helper files (Conan.io does this for multi-config generators). #3420
• Fix harmless warning on upcoming CMake 3.22. #3368
• Fix 2.8.0 regression with MSVC 2017 + C++17 mode + Python 3. #3407
• Fix 2.8.0 regression that caused undefined behavior (typically segfaults) in make_key_iterator/make_value_iterator if dereferencing the iterator returned a temporary value instead of a reference. #3348

Version 2.8.0

New features:

• Added py::raise_from to enable chaining exceptions. #3215
• Allow exception translators to be optionally registered local to a module instead of applying globally across all pybind11 modules. Use register_local_exception_translator(ExceptionTranslator&& translator) instead of register_exception_translator(ExceptionTranslator&& translator) to keep your exception remapping code local to the module. #2650
• Add make_simple_namespace function for instantiating Python SimpleNamespace objects. #2840
• pybind11::scoped_interpreter and initialize_interpreter have new arguments to allow sys.argv initialization. #2341
• Allow Python builtins to be used as callbacks in CPython. #1413
• Added view to view arrays with a different datatype. #987
• Implemented reshape on arrays. #984
• Enable defining custom __new__ methods on classes by fixing bug preventing overriding methods if they have non-pybind11 siblings. #3265
• Add make_value_iterator(), and fix make_key_iterator() to return references instead of copies. #3293
• Improve the classes generated by bind_map: #3310
  • Change .items from an iterator to a dictionary view.
  • Add .keys and .values (both dictionary views).
  • Allow __contains__ to take any object.
• pybind11::custom_type_setup was added, for customizing the PyHeapTypeObject corresponding to a class, which may be useful for enabling garbage collection support, among other things. #3287

Changes:

• Set __file__ constant when running eval_file in an embedded interpreter. #3233
• Python objects and (C++17) std::optional now accepted in py::slice constructor. #1101
• The pybind11 proxy types str, bytes, bytearray, tuple, list now consistently support passing ssize_t values for sizes and indexes. Previously, only size_t was accepted in several interfaces. #3219
• Avoid evaluating PYBIND11_TLS_REPLACE_VALUE arguments more than once. #3290

Fixes:

• Bug fix: enum value's __int__ returning non-int when underlying type is bool or of char type #1334
• Fixes bug in setting error state in Capsule's pointer methods. #3261
• A long-standing memory leak in py::cpp_function::initialize was fixed. #3229
• Fixes thread safety for some pybind11::type_caster which require lifetime extension, such as for std::string_view. #3237
• Restore compatibility with gcc 4.8.4 as distributed by ubuntu-trusty, linuxmint-17. #3270

Build system improvements:
