Path encoding for cross-method utility functions

[Jieran-S]

Following the discussion in #230 : If we have a utility function to convert resolution to n_clust store in /method/search_res,py, and we use this function in multiple methods, currently this is how we load the function in our scripts:

SpaceHack2023/method/scanpy/method_scanpy.py

Lines 152 to 160 in 3f7a160

	# import res-n_clust tuning function
	import sys
	from pathlib import Path
	# Add the parent directory of the current file to sys.path
	method_dir = Path(__file__).resolve().parent.parent # Navigate two levels up
	sys.path.append(str(method_dir))
	from search_res import binary_search

Yet this current solution is not ideal as it is hard to track which method uses this function. Is there any better idea to deal with this issue?
