Only stage examples with EXAMPLES.

Changes since 4.4.3:

• Added support for multiple receiver instances.
• irparams_struct irparams is now member of IRrecv.
• Removed return value for all decodePulseDistanceWidthData() decoding functions, which returned a constant true.
• Removed parameter aEnableLEDFeedback in function IRsend::begin(bool aEnableLEDFeedback, uint_fast8_t aFeedbackLEDPin) and IRsend::begin(uint_fast8_t aSendPin, bool aEnableLEDFeedback, uint_fast8_t aFeedbackLEDPin).
• LED feedback is always enabled for sending.
• Added output for UNKNOWN protocol to printIRSendUsage().
• Added experimental sendVelux().
• Added sendMaranz().
• Fixed bug in ReceiveDemo.cpp if DEBUG_BUTTON_PIN is not defined.
• Fixed minor bugs in Denon decoder.
• New handling of MARK_EXCESS_MICROS without strange rounding inconsistency.
