Added Extended NEC Protocol to TinyIR (#1200) 

Added the option to receive Extended NEC using TinyIRReceiver with a USE_EXTENDED_NEC_PROTOCOL compile option. Tested working on an Uno R3. Functions similarly to the USE_ONKYO_PROTOCOL flag, mostly reusing its code. Documentation and example file TinyReceiver.ino updated to match.
