Widget: A speedometer type gauge

[keithknott26]

Consider implementing a speedometer / tachometer type gauge where you can set the 0 and max value. Similar to the donut but can be used for reporting network throughput or latency metrics for example.

This is a great idea, thanks for suggesting it.

Most of the code written for the donut widget is reusable here, so this won't be too much work. The only thing that we have to figure out is how to handle the two colors (where they meet on the half-circle).

Specifically the braille canvas gives us sub-cell resolution (pixels). However when it comes to colors, we can only set color on the entire cell (all of tis pixels).
