update import script file
- Updated import script file to take csv files as input to import.
- Updated code to take input file name as command line argument. For some reason existing code is not able to take it as command line argument.
- Also updated code to insert default medicalCampPlace and staff table with id 1 without which code is running into Foreign Key Constraint Error. Ideally that data also needs to be imported via csv or other scripts, but for now inserting dummy data.
