Add dissector for CP "Cooper" 2179 Protocol 

All credit for development should go Qiaoyin Yang

CP2179 protocol is a serial based protocol. The 2179 protocol is implemented with minor variations between vendors.
The RTAC implemented the 2179 client supporting a limited function codes and command codes. The RTAC doesn't support
multiple function codes in a single request and the dissector also doesn't support decoding these or corresponding responses.
