Manual patch needed to get USB bridge working (AEGHB-97)

[redfast00]

I've tried to compile the wifi_router example in this project, with CONFIG_BRIDGE_DATA_FORWARDING_NETIF_USB=y, but this does not build:

/home/user/esp-iot-bridge/components/iot_bridge/src/bridge_usb.c:30:10: fatal error: tinyusb.h: No such file or directory
   30 | #include "tinyusb.h"
      |          ^~~~~~~~~~~
compilation terminated.

This is with the latest master. It should be noted that this feature is commented out in CI, so it doesn't appear broken: https://github.com/espressif/esp-iot-bridge/blob/master/.gitlab-ci.yml#L69

You can temporarily add the following patch to the code, and we will update the example for the NIC solution later.

@tswen Would you accept a PR that includes your patch?

Hi @redfast00 , there is an internal MR under review and will be released soon.

[chedim]

how soon, tho?

The current example can already use USB netif normally and does not require any modification to the components.
