minor clean up issues related to including the config file data classes

[mschwamb]

• sorchaConfigs.py has a whole bunch of functions that replace using other functions like PPGetIntOrExit() confirm if we still need PPGetIntOrExit() if it such functions should be removed
• remove commented out line

  sorcha/src/sorcha_cmdline/run.py

  Line 166 in 6ff172b

  # configs = PPConfigFileParser(cmd_args["configfile"], cmd_args["surveyname"])

• remove unused functions in PPConfigParser.py that are not used
• ensure that all config variables in the data classes are outputted to the log
• remove all unused old function tests related to the old method for parsing the config file

@Little-Ryugu - little things to do on cleanup for the config file parsing upgrades - this is for Jan - just ignore until you're back from winter break
