   Generate 'size' bytes of compressible data into 'buffer'.

   'LitProba' is optional, it affect variability of individual bytes. If litProba==0.0, default value will be used.
   Generated data pattern can be modified using different 'seed'.
   For a triplet (matchProba, litProba, seed), the function always generate the same content.
