Fix HDF5 OSX intermediate group creation errors (#1741)

Still not sure what the original problem was, but going through the HDF5 C++ API seems to fix the following error occurring in `amici::hdf5::hdf5CreateGroup` with recent HDF5 versions on OSX: 
```
>       return _amici.writeSolverSettingsToHDF5(*args)
E       RuntimeError: Failed to create group in hdf5CreateGroup: ssettings

../sdist/amici/amici.py:6129: RuntimeError

``` 

`H5::LinkCreatPropList::setCreateIntermediateGroup` was only added in HDF5 1.10.6, but current Ubuntu LTS still comes with HDF5 1.10.4. Therefore we still need to keep the C version.
