Memory leaks in multi_client_server.c:213

[LancyRiver]

Hello, there is a memory leak in lib60870/lib60870-C/examples/multi_client_server/multi_client_server.c:213.

In the directory lib60870/lib60870-C/examples/multi_client_server，this pointer newAsdu in multi_client_server.c:213 is not freed in the end. It will cause memory leaks.

steps to reproduce:
I used gcc 9.4 and AddressSanitizer (export CFLAGS="-g -fsanitize=address" LDFLAGS="-fsanitize=address" before make) to build lib60870/lib60870-C/examples/multi_client_server.
Run this program multi_client_server.
Press the button Ctrl+C to terminate the program multi_client_server.

ASAN Output

$ ./multi_client_server    
^C

I think adding this line of code to multi_client_server.c:251 can fix it.
CS101_ASDU_destroy(newAsdu);

Hi.
Thank you for the hint.
I changed the example so it doesn't show the memory leak.

Thanks a lot!
