## Problem
The optimisation will sometimes try to minimiser some panels, in order to assign their budget to other, more useful panels, however, this can lead problems, e.g. ScatterBatch._filter_scatters will remove any muons with at least one high-uncertainty hit, i.e. all muons get removed.
Example:
Potential solution
A callback that automatically removes panels. This could trigger on e.g.
- once their scaled x or y span drops below a fixed threshold
- if the number of filtered muons exceeds a threshold (absolute or relative to batch size)
