[ndnSIM] how to add private member variable in class Intererst

[呂建德]

Hi

I also had the same problem , and happened that "TLV length doesn't match
buffer length".

I add the length of my value to the "totallength" , and it pops up that
messages.

Anyone knows how to fixed it step by step , I will appreciate very much
