optimize: don't put flate on large jpegs unless compression is high

Putting flate on very large JPEGs can cause performance problems in PDF viewers, subjectively anyway.

Improve passing of arguments to workers
...
The executor system was built around passing only a single
argument to workers, which was
always PageContext. For other tasks, all actual arguments were packed in
a tuple, which meant we needed intermediate functions to unpack the
tuple.
The situation is now rationlized and resembles how Python handles
argument passing to familiar multiprocessing tools.

Fix test failures on pikepdf 3.2.0 + pybind11 2.8.0
...
When compiled without pybind11 2.8.0, pikepdf supplies a shim to implement
pikepdf._ObjectMapping.values() which has subtly different semantics
from a true dict-like objects; in particular it supports
next(objectmap.values())
where a standard dict requires
next(iter(objectmap.values()).
pybind11 2.8.0 now implements .values() properly, meaning some misuses of
protocol in ocrmypdf fail.
If pybind11 < 2.8.0, pikepdf will
continue to offer its shim. If pybind11 >= 2.8.0, pikepdf does not add its shim.
Consequently no changes were needed in pikepdf.
