#include <MsgPacketizer.h> in multiple source files

I have 2 cpp files both contain a line #include<MsgPacketizer.h>

The code is compiled for Arduino

I have enabled logging:
#define MSGPACKETIZER_ENABLE_DEBUG_LOG

(but even with DEBUG_LOG disabled some multiple definitions still exist)

During linking I get an error:

Ahh... ok, I should try to fix that but maybe it takes some time...
Can you show me another multiple definitions without #define MSGPACKETIZER_ENABLE_DEBUG_LOG ?

commented

In the end I hacked it by creating a define DEBUG_EXTERN and if set replacing all declarations with extern definitions.

Unfortunately It seems I can't use Debugging and MSgPacketizer together because too much RAM is needed on my 2048 byte Arduino :(

@dwjbosman Sorry for the late reply, fix this issue in v0.2.15. Thanks!
