He-like TOTL label should become Blnd
For He-like multiplets, we report the total emission under a TOTL label.
9660 TOTL 1.08303m # total emission in He-like lines, use average of three line wavelengths
We should change the label to 'Blnd', by using the code for blends found in prt_lines.cpp. E.g., around line 500:
LinSv *lineMg2 = linadd(0.0,2798,"Blnd",'i',"Blend" );
lineMg2->addComponent("Mg 2",2795.53);
lineMg2->addComponent("Mg 2",2802.71);
