Merge pull request #7488 from bgilbert/jpeg-restart
Allow configuring JPEG restart marker interval on save

e572722479 Allow configuring JPEG restart marker interval on save
libjpeg allows specifying the marker interval either in MCU blocks or in
MCU rows.  Support both, via separate parameters, rather than requiring
callers to do the math.

4d7372bfd0 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.
