The FastRPC implementation is loosely related to the sensor shell. It is useful to provide interfaces over FastRPC for sensor DSP firmware, and enables the sensor shell to provide most physical sensors. However, the FastRPC implementation has no meaningful connection with the sensor shell in terms of code. Move the FastRPC implementation to the project root to make it more intuitive to install and use and to separate it from a distinct project.
