Rewrite necessary DSRA/PSRA scripts to handle Hazus xlsx

[tieganh]

Master HAZUS file should be called by PSRA/DSRA indicator scripts (or any other scripts) avoid syncing issues. Currently scripts are referencing the collapse probability file.

This switch could be made in python, based on current consequence script, which is already doing this. Note that it uses a module called xlrd, and recent versions of it have a different way of parsing excel sheets. Accordingly, I've just let my version of xlrd become outdated to avoid needing to change the script.
