The max value was being calculated as the product of the max line width, max layer thickness
and max feedrate but it should be calculated as the maximum of the products of the width,
thickness and feedrate for each individual line. i.e. calculate the flow for each line
and use the min and max values of the flows.
We encountered a case where the version upgrade changed the quality profile to a new one which was specific to the printer rather than a global profile. As the upgraded stack was being read from the project file, it would go look for the new quality profile in the workspace. That ID wouldn't be present in there, and so it would crash and pretend the project file is plain 3MF.
This change makes it fallback to the built-in profiles, for precisely such cases as when a version upgrade changes the stack.

We've seen from experience that people do end up with broken files, due to user-modifications and whatnot. Corrupting it further won't make things better for the user.

Should fix#9752 aka internal ticket CURA-8246 -- This makes the repetier case completely analogous to the other 'not-griffin' flavours (at least what concerns retraction amounts), and also neatly dove-tails with the first point things start to go wrong in the bug-report.
Some ultimakers tend to choke if you try and send a lot of materials in one go.
Previously we would also always send the materials on the main thread, which would also make
the interface freeze a bit. That should no longer happen.
The implementation of this is not really great, but since this is a hotfix i've opted to change
as little as possible.
CURA-8224
Not all printers support a firmware configuration here. Wouldn't want to ruin some people's old prints by adding unsupported commands in there, nor change the tried-and-true old parameters people already tested with.
Contributes to issue CURA-8219.
Previously, Arcus, Savitar, and pynest2d were being build with a missing sip flag. This led to Cura
getting `ValueError: PyCapsule_GetPointer called with incorrect name`, if those libraries were not
imported (even if they were unused).
This flag was added in the following commits:
* 83393f989c
* e9e530d963
* bd440b50ad
Since the issue seems to be gone now, the unused imports should be removed from Cura.
All credits go to Rex Dieter for figuring that this missing flag was the issue.
