get_repeat_event_types function

Add identification for repeat event types

To correctly assign repeat event types a few assumptions must be made:

• There are only 3 behaviors: nonrepeating, repeat_separately, and repeat_together

• If an event only shows redcap_repeat_instance and redcap_repeat_instrument

  as NA, it can be considered a nonrepeat event.

• If an event is always NA for redcap_repeat_instrument and filled for redcap_repeat_instance

  it can be assumed to be a repeat_together event

• repeat_separate and nonrepeating event types exhibit the same behavior along the primary keys of the data. nonrepeating event types can have data display with redcap_repeat_instancevalues both filled and as NA. If this is the case, it can be assumed the event is a repeating separate event.
