TopoBench Category: B2; Team name: TG; Dataset: Simplicial PPI (HIGH-PPI SHS27k + CORUM)

NOTE: This PR branches from branch 'ppi-data' which contains my A2 submission as it builds on top of it. The actual changes are less than github is showing because it compares diff with main. If we decide to merge this PR, we should first merge the A2 PR.

Note: Due to time reason I could not finish this PR. I have some files locally not pushed yet and did not have the time to run proper benchmarks/tests and write documentation. I will add this and refactor the code once the challenge is officially over.
