Fixed - preprocess - actions

Resolution for #477 - fix verified using preprocessor tutorial.

We discussed that the desired changes should be made throughout the codebase before closing this issue or merging a branch.

One general thought after reviewing is that as a user, I would not be sure how to set random seeds to ensure reproducibility. Internally, several different packages generate random numbers, so the user would need to set random seeds for random, pandas, torch, and potentially numpy as well. I'm not sure what to do about this, but I'll create a separate issue for it.

The code to set seeds for all random methods across packages is a set of 4-5 statements that we can include in the documentation. Regarding the modifications, on second thought, instead of doing a sweep across the entire codebase, we could do it module wise with proper testing to ensure minimal risk. Have completed preprocess and annotations, will continue to do more before we do 0.8.0 release. The issue and branch could be kept open for working on other modules for subsequent releases.
