Change directory architecture to use 2 separated projects.

Each projects, binder and generator, has to be compiled separatly.
CAN-binder will host high and low level binding
CAN-config-generator only the generator used for low level binding.
build.sh script just launch both build in their respective dir.

+///
+/// This object is also used to initialize can_bus_dev_t object after reading
+/// json conf file describing the CAN devices to use. Thus, those object will read
+/// on the device the CAN frame and push them into the can_bus_t can_message_q_ queue.
+///
+/// That queue will be later used to be decoded and pushed to subscribers.
