New Backends, Extension, Perf. & Memory

ADIOS2 Joined arrays, API simplification, HDF5 subfiling, TOML
backend, wildcard file extensions, Performance & Memory: This release
adds support for additional I/O features in all backends, and
additionally a completely new TOML backend, useful for
openPMD-formatted configuration files in scientific workflows.
The ADIOS1 backend, previously deprecated, has been removed in favor
of ADIOS2.

The openPMD-api has been simplified by no longer requiring explicit
specification for scalar components via ``RecordComponent::SCALAR``
in its object model. The addition of wildcard filename extensions
(e.g. ``simData.%E`` or ``simData_%T.%E``) simplifies the generic
implementation of backend-independent logic, such as post-processing
routines.

Python, ADIOS2 and HDF5 Fixes

This release fixed regressions in the Python frontend as well as the
ADIOS2 and HDF5 backends. Supported macOS versions are now 11.0+ and
Python versions are 3.8+.

…mance & Memory

This release adds error recovery mechanisms, in order to access
erroneous datasets, created e.g. by crashing simulations. The BP5
engine of ADIOS2 v2.9 is fully supported by this release, including
access to its various features for more fine-grained control of
memory usage. Various I/O performance improvements for HDF5 are
activated by default. Runtime configuration of openPMD and its
backends, e.g. selection of backends and compression, is now
consistently done via JSON, and alternatively via TOML for better
readability. The data storage/retrieval API now consistently
supports all common C++ pointer types (raw and smart pointers),
implementing automatic memory optimizations for ADIOS2 BP5 if using
unique pointers.

The miminum required C++ version is now C++17. Supported Python
versions are Python 3.10 and 3.11.

Improve Series Parsing, Python & Fix Backend Bugs

This release improves reading back iterations that overflow the
specified zero-pattern. ADIOS1, ADIOS2 and HDF5 backend stability
and performance were improved. Python bindings got additional wheel
platform support and various smaller issues were fixed.

Increased Compatibility & Python Install Bug

This release fixes various read/parsing bugs and increases
compatibility with upcoming versions of ADIOS and old releases of
Intel `icpc`. An installation issue for pip-based installs from
source in the last release was fixed and Python 3.10 support added.
Various documentation and installation warnings have been fixed.

Read Bugs, C++17 Mixing and HDF5 Performance

This release makes reads more robust by fixing small API, file-based
parsing and test bugs. Building the library in C++14 and using it in
C++17 will not result in incompatible ABIs anymore. HDF5 1.10.1+
performance was improved significantly.

Various Reader Fixes

This releases fixes regressions in reads, closing files properly,
avoiding inefficient parsing and allowing more permissive casts in
attribute reads. (Inofficial) support for HDF5 vlen string reads
has been fixed.

ADIOS2 Close Regressions & ADIOS1 Build

Fix a regression with file handling for ADIOS2 when using explicit
close logic, especially with interleaved writes to multiple
iterations. Also fix an issue with ADIOS1 builds that potentially
picked up headers from older, installed openPMD-api versions.
