closecity 1.5.0

Multi-origin calls. block_summary, block_pois, point_summary,
point_pois, and poi_catchment now accept many origins in one request:
pass a list of GEOIDs (or dest_ids), or a list of (lat, lon) points, and
the whole set is queried in a single call — one request against the
300/minute rate limit instead of one per origin. Results come back as a flat
frame tagged by origin (geoid, or origin_lat / origin_lon, or
dest_id); per-origin errors and any truncated origins ride on
df.attrs. A batch is charged only for what the account can pay for, so a
huge query stops at the balance rather than overspending.
