Issue: #44 #48 #52

💻 What does this address?

Addresses listed issues in pyRACF's error handling and associated processing.

1. Adds new error for Null Response from IRRSMO00
2. Standardizes SecurityRequestError structure
3. Adds "install script" to define/check authorizations for IRR.IRRSMO00.PRECHECK

📟 Implementation Details

1. Checked for null string response from IRRSMO00 and throw new error if so
2. Define new methods of SecurityRequestError to restructure IRRSMO00 response XML with IRRSMO00 error to more closely align with RACF-error structure
3. Added "Scripts" folder and defined externally available function that checks active user's access to IRR.IRRSMO00.PRECHECK and creates the resource if possible.

📋 Is there a test case?

Designed new test cases for new error and install script under "common" test cases. Tested new SecurityRequestError functions with existing user and group error tests
