Documentation states that get_last_received_report() function should return None if there was no report received previously, otherwise it should return report. Moreover, same report should be returned only once. That makes it possible to reliably process incoming OUT/Feature reports. This patch adds an array that stores flags if report with particular ID was received and updates get_last_received_report() to match its documentation.
