break it and find out how to prevent that

[ModischFabrications]

1. Many Jobs
2. Invalid Jobs
3. Huge Jobs
4. Weird random stuff I know nothing about (Schmiddi?)

[ModischFabrications]

append to Job.valid():

• all lengths < max_length (what about the cut width?)

[ModischFabrications]

Length check works, invalid jobs are more or less checked. Huge jobs as in huge json is difficult to test right, skipping for now. many concurrent jobs will slow down the solver, but shouldn't break anything.
