====== Intel HEX ======
A data format for storing binary data as ASCII text. It consists of a sequence of //records//, which consist of the following fields:

  - start code ('':'')
  - byte count (1 byte)
  - address (2 bytes)
  - record type (1 byte)
    * data (''00''): the data field contains n bytes, where n is the byte count
    * EOF (''01''): the final record in the file; the data field is empty
    * extended segment address (''02''): the data field contains 2 bytes which are multiplied by 16 and used as the base of subsequent record addresses
    * start segment address (''03''): the data field contains 4 bytes specifying the start execution address for 80x86 processors, where the first two bytes are the CS value and the last two bytes are the IP
    * extended linear address (''04''): the data field contains 2 bytes to be used as the high-order bytes (big-endian) of 32-bit addresses for subsequent records
    * start linear address (''05''): the data field contains 4 bytes representing the big-endian 32-bit start address
  - data (n bytes), possibly empty
  - checksum (1 byte), calculated as the two's complement of the sum of the record contents

All values are stored as ASCII hex digits.
