Description

Add new script to generate open dataset with summary data per LSOA.

Prepare dataset for public sharing which includes summary data for each feature per LSOA.
Features to add:

median garden size estimate
property density
rural/urban status
proportion in building conservation area
proportion listed buildings
proportion with EPC C+
proportion of flats
proportion off gas
Also required: scores per tech type, n_properties, and use_weights/scores_weighted flag.

Instructions for Reviewer

In order to test the code in this PR you need to run the following command:
python -i asf_heat_pump_suitability/pipeline/run_scripts/run_generate_open_dataset.py --property_suitability s3://asf-heat-pump-suitability/outputs/2023Q4/20240905_2023_Q4_heat_pump_suitability_per_property.parquet --lsoa_suitability s3://asf-heat-pump-suitability/outputs/2023Q4/20240905_2023_Q4_heat_pump_suitability_per_lsoa.parquet -y 2023 -q 4

Please pay special attention to:

• The weighting of the proportional features and property density to check that it has been applied correctly. The code should calculate weighted proportions for proportional features only when weights have been used in the scoring. Otherwise, it should calculate unweighted proportions (i.e. they should use a weight of 1 per property). Note that for the median garden size estimate, I calculated the normal median rather than weighted median for simplicity.
• Check all key columns are included that we want to share.

Checklist:

• I have refactored my code out from notebooks/
• I have checked the code runs
• I have tested the code
• I have run pre-commit and addressed any issues not automatically fixed
• I have merged any new changes from dev
• I have documented the code
  • Major functions have docstrings
  • Appropriate information has been added to READMEs
• I have explained this PR above
• I have requested a code review

thanks @crispy-wonton this looks great to me! ✨
The script ran and the output looks as it should.
