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.

ADIOS2 Close Regressions & ADIOS1 Build

Resize, Dask, openpmd-pipe and new ADIOS2 Iteration Encoding

This release adds support for resizable data sets.
For data-processing, support for Dask (parallel) and Pandas (serial) are added and lazy reader parsing of iterations is now supported.
ADIOS2 adds an experimental variable-based iteration encoding.
An openPMD Series can now be flushed from non-``Series`` objects and write buffers can be requested upfront to avoid unnecessary data copies in some situations.
