HDF5Array 1.33.6

Replace internal calls to rhdf5::H5Fopen(), rhdf5::H5Dopen(), and rhdf5::H5Gopen(), with calls to new internal helpers .H5Fopen(), .H5Dopen(), and .H5Gopen(), respectively.

An undocumented feature of rhdf5::H5[F|D|G]open() is that these functions won’t necessarily throw an error when they fail to open the file, dataset, or group. Instead they can return a FALSE (with a message). Internal helpers .H5[F|D|G]open() are thin wrappers around the rhdf5::H5[F|D|G]open() functions that detect this situation and throw an error.
