* 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
