Zoning evaluated against the point

PPR addresses are geocoded, not surveyed — a sale's position is as good as its address match (`rooftop_n` says how many are address-accurate). Beds, floor area, BER and asking price come from the matched daft.ie advertisement, not from the Register, and only where a match was found (`enriched_n`).
