/********************************************************************************
 *  Airconditional remote control decoder for:
 *
 *  ZH/JG-01 Remote control https://www.google.com/search?q=zh/JG-01
 *
 *  The ZH/JG-01 remote control is used for many locally branded Split airconditioners,
 *  so it is better to name this protocol by the name of the protocol rather then the
 *  name of the Airconditioner. For this project I used a TACHIAIR airconditioner.
 *
 * For airco-brands:
 *  Tachiair
 *  Chigo
 *  Etc.
 *
 ***********************************************************************************
 *  SUMMARY FUNCTIONAL DESCRIPTION
 **********************************************************************************
 *  The remote sends a 6 Byte message which contains all possible settings every
 *  time.
 *
 *  Every EVEN Byte (00,02,04,06,08 and 10) hold command data
 *  Every UNeven Byte (01,03,05,07 and 09)  hold a checksum of the corresponding
 *  command by inverting the bits, for example:
 *
 *  The identifier byte[0] = 0xD5 = B1101 0101
 *  The checksum byte[1]   = 0x2A = B0010 1010
 *
 *  So, you can check the message by:
 *  - inverting the bits of the checksum byte with the corresponding command, they
 *    should be the same, or
 *  - Summing up the checksum byte and the corresponding command,
 *    they should always add up to 0xFF = B11111111 = 255
