Alternatively we can only pass the wIndex to getDescriptor but I suggest to just pass the pointer aka reference of the whole setup.
In guess (havent tested this) that this results in more or less the code size but its a) idential with the other functions and b) we late have more flexibility here.
The Code got a quick SerialKeyboard.ino test
The check for available slot in PluggableUSB is done on the endpoint
and not on the number of plugged modules.
The modulesCount field is no longer useful and it has been removed.
The method
int8_t PluggableUSB::addFunction(PUSBListNode *, uint8_t *)
has been changed to
bool PluggableUSB::plug(PUSBListNode *node)
since both EP and Interfaces are now saved directly into node
