A position a host asks MAIDR to move its cursor to.
The inbound counterpart of NavigateCallback, spelled in the same
currency so a host can hand back what it was given: a {row, col} cell for
a grid-shaped trace, or a pointIndex into the layer's data array for a
point cloud, where no row/column pair names a mark. It is what lets a
click in the host's own chart -- a Tableau mark, a canvas hit-test -- land
the reader on the same mark, so a sighted colleague pointing at a bar and a
screen-reader user reading the chart are on the same one.
Delivered through window.maidrLive.navigateTo or navigateMaidr; see
docs/LIVE_DATA.md.
