Support for sending consumer control codes

[DJFliX]

@arturo182 Thanks for this amazing project! Ever since I received my BBQ20KBD I've been fascinated by the project and the firmware. I've been tinkering with it and I think that I do now have some understanding of the overall structure of the code in this project.

The goal I'm trying to accomplish is the following: I'd like to bind KEY_BTN_LEFT2 to sending a keycode that triggers HOME on Android (so: navigating to the launcher). I'd like to try using some keycodes on the 0x0C page (Consumer Control) to achieve that.

Looking at the tinyusb library I can see that buttons in the 0x0C page (Consumer Control) can't be sent using tud_hid_n_keyboard_report. Instead the more generic tud_hid_report has to be used. Any attempts I have made so far have resulted in various compilation errors.

Is adding 0x0C page support something that's on your roadmap as well? Otherwise I'll continue my attempts at bruteforcing this at a later point in time :).
