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.
