Get Kalshi Orderbooks V2

Fetch historical sub-cent orderbook snapshots for a Kalshi market.

Identical in shape to /orderbooks, but prices are decimal-cent strings (e.g. "36.50") instead of integers, and each snapshot carries a source field. All timestamps are in milliseconds.

The default (sources=spine) serves the standard capture streams; experimental streams are excluded unless sources=all is passed.
