Allow option to just return icon (or card visual with icon?)

[Bergam0t]

Possibly build in as a sort of custom KPI visual? As icons alone being added to KPI visuals could result in a lot of visuals to load per page.

Custom card visual could support that.

Show most recent value, variation icon, assurance icon if present, sparkline (with marker colours?).
Option to turn various elements on and off.

Font options + various built-in standard visual options should be sufficient.

Have implemented the card. Can now select 'Card' from output type. Produces card visual containing most recent value, KPI icons, title, and small version of the SPC chart.

Leaving open to decide whether to create an option that just returns the icon.
