klipper: Improve performance

[timiv]

This slightly improves the performance of klippy by disabling assertions and debug statements in python.

@timiv There's already another pr open (#55 ) that might be more interesting. Also, wouldn't it make sense to do -OO?

[timiv]

@suchmememanyskill It seems like #55 only tackles RAM usage not CPU load. I had issues with some tight arcs (G3) recently where single core performance was insufficient for the gcode_arcs: 0.1 we use. Together with #41 I was finally able to successfully print the model.

This change does not lead to significant improvements, though.

As far as I understand -OO only disables docstrings, in addition to -O and does not affect performance in a meaningful way.

After reviewing #55, I decided to add -OO . We either need to integrate this with #55 or merge it before. #55 only compiles python modules with -OO but does not seem to call python with proper flags.

I haven't tested this, but i don't see how this would break tbh. Merging
