print the lines always in one direction
print from two sides into a center of the objects

Description

When printing flow calibration using "old style" monotonic lines, print the lines always in one direction, to prevent print asymetry/inconsistency due to printer move error (as e.g. mentioned here: https://github.com/SoftFever/OrcaSlicer/pull/10314 )

The printing of the lines is also split to 2 halves, each half is printed from the cornet. This makes in the middle "bump" effect similar way, like when using archimedean flow.

Tests

Printed 2 batches, one is on the picture above. This batch doesn't have the lines printed in the same direction through all objects, but it's already fixed in the code for better consistency. The first archimedean test is +03 when compared to others, I just had it already printed and changed the flow in settings after it. The rest is printed with the same exact settings of course.
