Remove unused variables

[bear-is-asleep]

Unused variables cause misallocated memories, and segmentation faults within cluster3D.

This fixes a lot of seg fault instances I've seen in Cluster3D. Further debugging is needed to fix them all.

@bear-is-asleep since more debugging is needed in the future, can you please create an issue and link this PR to it so we can keep track of all updates related to Cluser3D?

@bear-is-asleep i see you turned this into a draft. Is the PR as is not ready to be merged? Or do you want to fix all the segfault issues before merging everything at once?

It caused a really strange issue where downstream TTrees are not filled from analyzer modules (i.e. Supera). So it's not ready to be merged since it breaks Supera.
