allow HID submodules to create runtime descriptors
with this PR you can add
\#include Keyboard.h
\#include Mouse.h
\#include HID.h
in the top of the sketch and you will expose a Mouse+Keyboard
From the library pow, simply add
static HID_Descriptor cb = {
.length = sizeof(_hidReportDescriptor),
.descriptor = _hidReportDescriptor,
};
static HIDDescriptorListNode node(&cb);
HID.AppendDescriptor(&node);
in the class' constructor and you are done!
