Subject: [PATCH] Update readElkfiles.py

During the Elk conversion process, two files, SYMCRYS.OUT and LATTICE.OUT, need to be read. However, after the Elk calculation is completed, there are some blank lines in these files, which leads to recognition failure of readElkfiles.py.  By using line.strip(), non-blank lines can be directly read.
