the building process and runs the process.
If --screen is selected, the prompt returns to the user after launching Bela in a screen on the target device.
If --screen and --watch are combined, while the process is running in the screen, modifications to the source files will \
still trigger a new build.
-r allows to build against a specific Heavy release. Default is the most recent version.
