This pull request fixes #12.
The root cause was [`BLE_HandleCommonEvents()`](https://git.ktag.clubk.club/Software/SystemK/src/tag/SystemK_v01.01/BLE/BLE_Utils.c#L57) was causing BLE events to be marked as "not new" by [`BLE_IsPacketNew()`](https://git.ktag.clubk.club/Software/SystemK/src/tag/SystemK_v01.01/BLE/BLE_Packet_Tracker.c#L53), even though these packets were left unhandled by the common event handler.
The solution is to separate the querying of whether a packet is new from the marking it as already seen, since we don't want to mark a packet as seen until it has been properly _handled_. I added the function `BLE_RememberPacket()` for the latter purpose.
I also cleaned up some of the logging code, now that logging is configurable (on ESP32 platform, anyway).
