BaseFhirTypeConverter Does Not Support Integer Intervals

[jreyno77]

toFhirInterval does not support Integer Intervals:

Cql: define "AnyInterval": Interval[2, 7]

switch (getSimpleName(value.getPointType().getTypeName())) {
            case "Date":
            case "DateTime":
                return toFhirPeriod(value);
            case "Quantity":
                return toFhirRange(value);
            default:
                throw new IllegalArgumentException(String.format(
                        "Unsupported interval point type for FHIR conversion %s",
                        value.getPointType().getTypeName()));
        }

There's no mapping defined for an FHIR Period or Range using FHIR Integers. See the mapping spec here:
