BUG-FIX: the hydrogenic xs were raising an exception when Z<13 and Z>36 because Egerton's original code was not designed to work out of this range
Add correction factor parameters for Na and Mg to the Hydrogenic XSs so that they better match HS XSs
Rename mapped parameters in examples (forgotten in previous commit)
Merge branch 'master' into ENH_hydrogenic_xs
