Can't correctly display Code128

[zhtzeng]

There are two issues.

1. According to your codes, this plugin only display code128B.
   Code128C is compression format if there are only digits
2. I am trying to take byte array as input instead of string.
   Since code128 can be mixed with code128a/code128B/code128C.
   For example,
   1645907 is code128c with last digit is code128a
   The real raw bytes are 105, 16, 45, 90, 101, 23, 73,106
   101 indicate code128a is used and therefore, 23 represents '7' (not '07' in code128c)
