{:ok, <<5, 16, 104, 101, 108, 108, 111>>}
  
iex> Snappyrex.decompress(<<5, 16, 104, 101, 108, 108, 111>>)
{:ok, "hello"}
  
iex> Snappyrex.compress("hello", format: :frame)
{:ok, <<255, 6, 0, 0, 115, 78, 97, 80, 112, 89, 1, 9, 0, 0, 187, 31, 28, 25, 104, 101, 108, 108, 111>>}
  
iex> Snappyrex.decompress(<<255, 6, 0, 0, 115, 78, 97, 80, 112, 89, 1, 9, 0, 0, 187, 31, 28, 25, 104, 101, 108, 108, 111>>, format: :frame)
