 * This function searches for EMM keys and adds their Unique Addresses (UA) as EMM filters.
 * The EMM keys are picked from all group id's that have ECM keys for the srvid specified
 * as input. If there is a large ammount of EMM keys matching these criteria, only the first
 * "maxCount" UA's are added as EMM filters. The rest are not used at all.
 *
 * In the rare case where two or more EMM keys with the same UA belong to different groups,
 * and these groups also have ECM keys for the srvid in request, there is a chance the ECM
 * keys in the "wrong" group to be updated. This is because the EMM algorithm has no way of
 * knowing in which group the service id belongs to. A workaround for this designing flaw
 * is to make sure there are no EMM keys with the same UA between different groups.
 *
 * Hexserials must be of type "uint8_t hexserials[maxCount][4]". If srvid is equal to 0xFFFF
 * all serials are added (no service id filtering is done). Returns the count of hexserials
 * added as filters.

 * new method of entering ECM keys, where one key can serve every channel in the group. Since
 * there is no srvid to search for, we need to know the group id prior to searching for EMM
 * keys. To do so, this function calulates a hash using the tsid, onid and enigma namespace of
 * the transponder, which is only available in enigma2.
 *
 * Hexserials must be of type "uint8_t hexserials[maxCount][4]" like before. It returns the
 * count of hexserials added as filters.
