add prepop cql file

[KeeyanGhoreshi]

Adds the files needed for doing the prepopulation, including the CQL file and a couple changes to the library and questionnaire files. Note that there are two new valuesets that are required for use, so you will either have to provide a VSAC API key in your environment or manually reload the data at http://localhost:8090/data using your VSAC API key.

Small note that several of the codes which are defined directly in the CQL could also be converted into valuesets, which can be done if needed/wanted.

Also note that the prepopulation will "fail" to fill out the hepatic medical history section of the questionnaire, only including an [Object object] as the answer. This is actually a failing of lforms (or DTR, I'm not exactly sure). I had originally thought it was the result of the CQL formatting the answer incorrectly, but the same issue appears if you manually select an item from the list and then check and uncheck the box.

This problem is outside of the scope of this task, and if it functioned properly, I'm almost certain it would be prepopulated correctly given that the method used in the CQL file is identical to how every other prepopulation file in DRLS fills out a choice question.
