User input logic and display handling

Controller to abstract the GUI and TUI control.

Handles the linking of user input and sof_ctl generically of the control type.

Build sof-ctl for target and copy it to the gui folder base directory within your local repo.

If you have audio on your local machine that you wish to demonstrate using the GUI, add it to the audios subfolder. Also, you can specify audio paths on the target with the command line arg --audio-path "path"

If you would like to include eq configs, they are stored in tools/ctl/ipc3. Copy them from there to the eq_configs folder.

Copy entire GUI folder to target hardware.

Next, ensure that the sof-<hardware-name>-gui-components-wm8960.tplg is built and loaded as SOF's topology. Make sure this is built for your target hardware.

After this, run either the GUI or TUI on a board with SOF loaded. This can be done using the command: python3 sof-demo-gui or python3 sof-demo-tui

The interfaces themselves are self-explanatory, as they are made to be plug and play on all SOF supporting systems.

The features currently supported are: Playback and Record with ALSA Volume control using the SOF component EQ component with realtime control Generic implementation with autodetection of SOF cards and commands
