Writes six tidy CSVs to data/processed/: income_by_source.csv, income_by_source_gender.csv, income_by_age.csv, tax_burden.csv (all TEK01001 cuts) plus total_income_distribution.csv (TEK01006) and employment_income_distribution.csv (TEK01007).

Code cheatsheet — Tekjur og skattar: 0=Heildartekjur, 1=Atvinnutekjur, 2=Fjármagnstekjur, 3=Aðrar tekjur, 4=Skattar, 5=Ráðstöfunartekjur (disposable). Eining: 0=mean, 2=median. Kyn: 0=all. Aldur: 0=all, Y16-64, Y25-54, 5-year bands 16–85+.

Gotchas that bite:

• Values are in thousands of ISK, not ISK — 8080 is 8,080,000 kr.
• Eining=2 is the median, not a second mean — treating both columns as means silently double-counts.
• The PX response is UTF-8 with a BOM — decode utf-8-sig or the first header carries \ufeff.
• Income-type rows include taxes (4) and disposable income (5) — never sum across rows to get "total income"; 0 is already the total.
