/* RDG_genBuffer
   Generate 'size' bytes of compressible data into 'buffer'.
   Compressibility can be controlled using 'matchProba', which is floating point value between 0 and 1.
   '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.

   RDG_genStdout
   Same as RDG_genBuffer, but generates data into stdout
