Edit the concentration parameter of a saved HDF5 file
=====================================================

Loads in a previously saved HDF5 dataset. If the attribute
'concentration' does not exist in the acq_params, this will 
add the concentration defined by 'actual_conc' into acq_params
under 'concentration'. If the attribute already exists it will
simply replace the current concentration with the value of 
'actual_conc'.
