20Q2 - Removing unused files and rewrite export and archive scripts

[ ] everything under _sql folder, note that everything in _sql will be preserved in the current master branch, which we will rename as archive once dev is complete

Under `data`

[ ] corrections_qc_outliers.csv --> not used?
[ ] housing_input_dcpattributes.csv --> not used?
[x] housing_input_lookup_occupancy.csv
[x] housing_input_lookup_status.csv
[x] housing_input_removals.csv --> this is no longer relevant because it only records bistest jobs, which we can remove without recording, according to HED
[ ] housing_input_hny_job_manual.csv --> not used in any of the current scripts???
[ ] housing_missing_jobnum.csv --> ??
[x] qc_outliers.csv --> qaqc to output
[x] qc_outliersacrhived.csv --> qaqc to output

[ ] geocoding.md --> out of sync with current methodology and we will rewrite in wiki
[ ] housing_input_convert.py --> not sure what this is for?
[ ] aggregate_ct.py --> not sure what this is for?
