Fish real time update cycle

Components

Fish constists out of the following components:

• I/O update module: Runs a libev event loop for network / ArtNet traffic as well as IPC and FPGA communication
• Cycle module that loads the correct execution engine (direct or filter), executes it and triggeres the output of new packages
• On demand module that loads filter sets from a given project file
