Increase USBHID::maxHidInterfaces from 3 to 5

Browse source 
It's not that uncommon to have more than three HID interfaces in a
USB device - even an Arduino Leonardo (or Pro Micro) always has
two just for the CDC; if you add a Boot Keyboard HID interface and
one generic HID interface for consumer control (multimedia) keys
you already have four..
Many commercial gaming keyboards also have more then three interfaces
(I don't think they really need that many but it is what it is).
