Ascent/Descent Rate Calculation Issues

[darksidelemm]

Something is not right in the ascent/descent rate calculations on the tracker. They seem to over-read the ascent and descent rates. This might be something to do with changes made to the calculations recently.

Ascent rate calculations are done around here: https://github.com/projecthorus/sondehub-amateur-tracker/blob/main/js/tracker.js#L2707

Thing to look into:

• Check incoming telemetry is de-duped properly before it is used for these calculations.
• Check the filtering is working correctly
• Use ascent_rate field data if it is provided in the telemetry if it is available.

Have reverted a bit of the calculations as a test, it's possible working better?
We're not just using the previous to current position, and filtering the ascent rate.
