Method sendNECMSB

src/ir_NEC.hpp:394–409

* With Send sendNECMSB() you can send your old 32 bit codes. * To convert one into the other, you must reverse the byte positions and then reverse all bit positions of each byte. * Use bitreverse32Bit(). * Or write it as one binary string and reverse/mirror it. * Example: * 0xCB340102 byte reverse -> 02 01 34 CB bit reverse-> 40 80 2C D3. * 0xCB340102 is binary 110010110011010000000001000000

 * If you read the first binary sequence backwards (right to left), you get the second sequence.
