* Handle scale_factor and add_offset as scalar

The h5netcdf engine exposes single-valued attributes as arrays of shape
(1,), which is correct according to the NetCDF standard, but may cause
a problem when reading a value of shape () before the scale_factor and
add_offset have been applied.  This PR adds a check for the dimensionality
of add_offset and scale_factor and ensures they are scalar before they
are used for further processing, adds a unit test to verify that this
works correctly, and a note to the documentation to warn users of this
difference between the h5netcdf and netcdf4 engines.

Fixes #4471.
