Convert an am5radar gauge into the single GaugePoint it draws.
A single object rather than an array, because the chart draws exactly one
measure — an array of one would describe a shape the chart does not have.
null when the dial has no finite ends. GaugeTrace pitches its tone
against the range rather than against the value, so a reading with no range
behind it is not a reading at all; emitting no layer is the honest answer,
and the caller then leaves the panel out rather than announcing a dial of
NaNs.
The range is read from the axis' own min/max settings, falling back to
the private values amCharts computes when the author did not fix them. It is
NOT read from the axis' start/end, which on an am5 axis are the relative
zoom positions (0 to 1) and would silently answer with a 0-to-1 dial for
every gauge whose extremes are computed.
