Ability to add in data element requirements outside of derived from measure elements

On top of measure-specific requirements, some additional data requirements may be needed and requested to run through MADFSH. This issue is to identify:
- determine a way to provide these requirements to MADFSH
- decide on how to incorporate them into the Profile generation

For example, this could be done through adapting:
- input: For the input step, the dataRequirements array could be created using the same format as the measure requirement that MADFSH processes. There should be entries for each resource type (no profile) with the list of element that are used for filtering in the mustSupport list.
- processing: For each profile of a resource type in the filter array, add each element in the mustSupport list as a mustSupport element in the profile - probably want to distinguish these in some way e.g., by adding the name of the additional requirement as another source for the summary table.
