3 Slots Route

This route receives a request for a list of all the available time slots for an appointment with a specific practitioner. The route extracts the requested information from the FHIR Server in the form of a FHIR Bundle and splits the data into separate files, one for each available slot. Each slot has its unique ID. The route batches the resulting files into a single message and sends the data back through an HTTP response.
