}Heatmap
Replay per-strike heatmap at a past instant (one or more symbols)
The snapshot nearest at for one or more symbols — same shape as
/v1/heatmap minus velocityPct (velocity is live-only). at may be
up to 365 days in the past; if no snapshot exists at/near that instant
the response is 404 with code: no_data.
