Add Telephony Device Page (0x0B) HID_DESCRIPTOR

[ThomasAtBBTF]

It would be very helpful if someone could add a sample HID_DESCRIPTOR for the Telephony Device Page (0x0B)
So we could make a ItsyBitsy Project to answer or decline incoming calls on an IPhone.
(And play with other Usages)

@ThomasAtBBTF do you mean over BLE or USB?

[ThomasAtBBTF]

BLE !

Then this could be done in the BLE library or an additional library. I'll move the issue there.

I think the "only" thing we need is a small collection of bytes that can be added to the standard HID Descriptor for advertising the peripheral capabilities.
I can try to come up with them by myself, but for someone with some experience with headsets and their capabilities to answer calls, switch between calls, and hang up, it will be "a piece of cake" to form an iPhone-compatible descriptor.

Supporting a telephony would be very useful as it would allow creating a "panic button" for old people so it calls their sons. I'd also make a nice kit with a nice red button.

Nobody has done this before and you would be the first one.
