Description

This adds a Svelte overlay to display live telemetry over camera feed.

How Has This Been Tested?

This has been tested using docker and running natively. It includes a MQTT producer for data for viewing changes.

Checklist:

• New functionality is documented in the necessary spots (i.e new functions documented in the header)
• Unit tests cover any new functionality or edge cases that the PR was meant to resolve (if applicable)
• The CI checks are passing
• I reviewed my own code in the GitHub diff and am sure that each change is intentional

Overall, looks great. Could you add a query string toggle for the synthetic data and a parameter for the MQTT address? Oh, and, can you run pnpm exec eslint --fix to fix linter issues (I'll add this check to CI at some point).

Regarding more nit-picky things, er, things that are entirely subjective; I think it would make a bit more sense to move the lat/long within the map's container to maintain a slightly better information hierarchy. In a similar way, the target values in the altitude and g-force sliders were a little unclear to me at first (I wasn't sure what they meant), so maybe changing the symbology of the set point can help.

Anyways, I'm not too bothered about testing it against real MQTT until I have a way to send fake data lol, which I will work on soon tm.
