Reads all modified data points from the file into a DataPointModified array. At least one data point before and after the time range must be included in the returned array, because a bounding value may be requested or interpolation needed. Excess data doesn't harm, it will be ignored in the base layer data processing. The returned data MUST be sorted for increasing timestamps. On error throw a HDAException with the error code that is to be returned to the client.
