Support read-slice input to `Viz.maxmin()`
Acts as short cut when pipe-lining from `Viz.update_graphics()` (which now returns the needed in-view array-relative-read-slice as output) such that `Viz.read()` and `.datums_range()` doesn't need to be called internally multiple times. In this case where `i_read_range` is provided we of course skip doing time index translations and consequently lookup the appropriate (epoch-time) index indices for caching.overlays_interaction_latency_tuning
