Compute speed for a track and visualize speed statistics in time and space

Is your feature request related to a problem? Please describe.

When we realize a Southern Resident killer whale (SRKW) is in nutritional distress (starving, peanut head) based on e.g. drone-based photogrammetry or other imagery of body condition, it is sometimes too late to intervene and have vets try to save the animal (e.g. J50 with parasite load). Rob Williams suggested in his 2/6/24 Salish Sea round table talk that swim speed or reduced dive duration of an individual might be an early precursor to poor body condition.

Could such metrics emerge from Acartia.io data -- either for the distressed individual's pod or matriline -- or even for the individual if enough photo IDs are obtained to define a track for them?

Describe the solution you'd like

For a visualized track of SRKW locations from Acartia.io, compute and display speed statistics. For example, hovering over a track's label (e.g. start or end icon?), the UI could show the mean and standard deviation of the speed for over the entire track. If individual track segments were hovered over, then the speed (and direction?) between the adjacent points could be displayed.

For a given region and/or time period, perhaps speed statistics for a suite of tracks could be visualized? Ideally, we'd be able to monitor the swim speed of each SRKW individual and detect any anomalously low swim speeds in near real time... (which would trigger an emergency notification!)
