Convert notebooks to scripts

[sgreenbury]

This PR closes #21 converting the preprocessing notebooks to scripts so that the downstream data is constructed for notebooks 3 and onwards.

Outstanding areas to look at refining:

• Make deterministic: set seed/random_state as part of input
• Write metrics that capture matching performance/quality to file for validation (relates to Validation framework for model #17)
• Flexible input to allow different sized samples upon running the script

[sgreenbury]

Perhaps can be an input parameter for the script to determine if run on the whole population?

Thanks for the readme! Everything else looks good to me, except I can't run the 1_prep_synthpop.py. I think this is an issue in my setup so can revisit it in the weekly meeting. Happy to merge this if @BZ-BowenZhang is ok with it also

There is no oa11cd and msoa11cd found in the region_people_hh.parquet

[BZ-BowenZhang]

I checked the output file from scripts/1_prep_synthpop.py, the column names are oa and msoa, I think that is the reason for this error

[BZ-BowenZhang]

The acbm package automatically installed from poetry does not have the processing sub-module, I had to manually move the processing.py into the folder to fix this issue

This error seems fixed when I ran poetry update again
