 signed integer will be returned to R as a
regular integer (can be changed using flags). Any HDF5 64-bit integer
can be returned as a signed 64-bit integer - with the option of
returning it as a 32 bit integer or double if it can be done without
loss of precision. For unsigned 64-bit integers, they will be returned
as floats, incurring loss of precision but avoiding truncation.</li>
