Implement streamtype=1 option for tables-only JPEG encoding
...
We already support streamtype=2 to skip producing JPEG tables, but
streamtype=1, which skips everything but the tables, was never implemented.
The streamtype=1 stub code dates to Git pre-history, so it's not
immediately clear why. Implement the missing support.
jpeg_write_tables() can't resume after a full output buffer (it fails with
JERR_CANT_SUSPEND), so it might seem that Pillow needs to pre-compute the
necessary buffer size. However, in the normal case of producing an
interchange stream, the tables are written via the same libjpeg codepath
during the first jpeg_write_scanlines() call, and table writes aren't
resumable there either. Thus, any buffer large enough for the normal case
will also be large enough for a tables-only file.
The streamtype option isn't documented and this commit doesn't change that.
It does add a test though.
