Speedup Accumulation process

[TravisH18]

A few parts of the Accumulation loop are bottlenecks at the moment.

1. make_all_cat_comids takes ~15 minutes.
2. Zone processing for loop in MakeVectors function takes ~80 minutes.
3. Bastards function itself takes ~2-3 minutes.

Generic parallelism and changes to libraries like pyogrio or doing numpy vectorization will give us massive speedups without having to alter code too much.

Created Speedup branch and pushed changes to makeVector process. This was the main slowdown in the accumulation process. Could continue working on children / bastard functions as well as adding numba to swapper function since it uses pure numpy processes.
