TDMS File Format Internal: the missing stuff

Missing from the descriptio on http://www.ni.com/white-paper/5696/en : TDMS File Format Internal Structure

The string fields have N_VALUES*32 bits / 4 bytes filed before the data pointing to each string value, starting at the end of the address field

## Example 

file : XXXXX.tdms
Start :  6221213 / 5EED9D
Channel: /'TM_SCIENCE_TIS_DATA'/'par_tis_bin_mode_txt:2'
RAW_DATA_DESCRIPTOR :
   DATA_TYPE       ULONG         32
   ARRAY_DIMENSION ULONG          1
   N_VALUES        ULONG64        8
   DATA_START_RAW  ULONG64  6221213
   TOTAL_SIZE      ULONG64      56

Hexdump fo the file from 6221213 to 6221213+56 = 6221269
The first 8*4 bytes = #2 bytes are the addresse to each signle text value.
