[Feature Request] Don't expand job-arrays

[VRehnberg]

Currently job-arrays are expanded into separate jobs (in squeue pending array jobs are contracted e.g. 2360362_[30-119%30). This leads to a lot of extra clutter to scroll through. With the option to toggle job-arrays into bundles or separate lines it would be easier and the default should be bundled for pending jobs.

Mostly useful for pending jobs (running jobs will have different elapsed time and different output files).
