Pull request overview
This PR adds a new template USB Audio application (app_usb_aud_template) intended as a starting point for porting the USB Audio framework to custom hardware. The template provides a minimal 2-channel input/2-channel output USB Audio Class 2.0 configuration with empty stub functions for hardware-specific customization, allowing developers to avoid the confusion of hardware-specific code from other reference designs.
Key changes:
- Added minimal template application with 2in/2out I2S audio channels
- Provided empty stub functions for hardware initialization and audio stream callbacks
- Included basic configuration files (xua_conf.h and .xn hardware description)

The casing of "Known Issues" should match the consistent pattern used in other README files. Based on app_usb_aud_xk_316_mc/README.rst line 38, this should be "Known issues" (lowercase 'i').

The idea with this is to provide a "blank" app as a good place to start a port to new HW.
Also we have quite a few users trying to run binaries for XMOS boards on custom hardware and getting stuck as these binaries are customised to configure specific external hardware.
