convert run_cfm_param_checks.py to a first class CLI module

[chrisbc]

/eq_fault_geom/geomio/run_cfm_param_checks.py needs to

• be moved into ../cli package
• use optparse package (or similar) to implement a simple Command Line Interface for the user
• remove any any hard-coded paths or files in the script
• provide a --help option telling the user how to use it.
