      public static void readArray(ByteBuffer inBuffer, int[] table, int size)
      Read a table from a two-level run-length encoded stream. The encoding first stores run lengths for each successive value (0, 1, 2, ...), using 255 as a continuation marker. A second RLE level compresses consecutive identical run-length values.
      Parameters:
      inBuffer - the input stream to read from
      table - output array to populate with decoded values
      size - number of elements to decode into the table
