Use binary file such as current-wf.bin, if available, instead of hydrogen_re-wf.dat.
Not only the latter's filename differs calculation case by case but also the reading speed to binary file is much faster.
The mechanism for determining default file name should be like searching a name of existing file from the prioritized list of default file name candidates. In that list, current-wf.bin is the first and hydrogen_re-wf.dat should be the second.
