    Read TIFF and EXIF information from a JPEG-format image.


    1. Retrieve data from a file:

            iex> {:ok, info} = Exexif.exif_from_jpeg_file(path)

       Retrieve data from a binary containing the JPEG (you don't need the whole
       thing—the exif is near the beginning of a JPEG, so 100k or so should
       do fine).

            iex> {:ok, info} = Exexif.exif_from_jpeg_buffer(buffer)

    2. Access the high level TIFF data:

            iex> info.x_resolution
            72
            iex> info.model
            "DSC-RX100M2"

    3. The exif data is in there, too.

            iex> info.exif.color_space
            "sRGB"
