splitting out some csv parsing functions

making the Processor.py pass on non-zero exit codes when exiting - I THINK THIS COULD CAUSE PROEBLEMS WITH INTEGRATION TESTS, AS IT WILL EXIT THE PYTHON ENVIRONMENT RATHER THAN CARRYING ON TO THE ASSERTS IF THERE IS AN ERROR, WILL ROLE BACK IF THIS IS THE CASE

fixing env suit half fat test (fewer output files now we have switched to using the mean of daily max as standard for env suit)

...in recent commits to ews-coordinator and ews-epidemiology.

allowing the full iontegration pipeline for Surveys to use the standard deployment config, rather than trying to exclude WRSIS

adding a check for loading resource files before all partial integration tests begin. Allows the user to spot if they have not set their working dir correctly
