Update logic For K.1.4 Heading 4.5 to check for two occurrences of CIN2/ungraded HSIL occur >=24 months and < 3 years of each other.

Would you mind adding a test or two for this scenario, since this is directly to address an issue with one of the Test Script patients? Something that shows that a patient with two CIN2 results a year apart will not get this recommendation, but that that a patient with CIN2 results two years apart will get this recommendation. Might be helpful to recreate Test Patient 37 from the Test Scripts spreadsheet, since this was the patient that led to the discovery of this issue.

Added three test cases: one recreates Test patient 37, one has 2x CIN2 1 year apart (doesn't get recommendation) and one has 2x CIN2 two years apart (gets this recommendation).
