Retire the "svelte-speedometer" in favor of an in-house one

[seofernando25]

Our current speedometer svelte-speedometer is just a wrapper over d3-speedometer.
This is a bit silly and their version is a bit outdated.

We want to have more control over it and reduce load times (one less library to load) so I figure it would be better to rebuild it from scratch.

Recreate this slider as seen in ccm's link and create a component to display some measurement: speed, error, rate, etc (use custom zones+color to convey meaning)
