Extraneous spaces in A617.xml file

[Matthew-Mullin]

file: https://github.com/Argonne-National-Laboratory/srlife/blob/master/srlife/data/damage/A617.xml

There are some extraneous spaces on lines 23 and 29 in the aforementioned file, which makes the file not readable to the destring_array function in srlife/materials.py for the temp ranges around 977.15 K and 1444.15 K
