For fixed-length strings that have a padding mode that suggests they're null-terminated are in fact not required to be null-terminated, we (silently) fail to read the last character. Since, HDF5 will create such string, h5dump will display the file and h5py will read the string; we opted to allow it and also read the string into and `std::string` (which is variable length and already not guaranteed to have the same length as the fixed length string). HighFive will continue to not allow writing null-terminated strings that aren't via `write`. Backports: (#1056)
