Removes spatial outliers by calculating lead and lag speeds (following Marta's code)
Removes altitude outliers by calculating lead and lag vertical speeds. I'm not confident at the threshold that I chose: >= 2 vertical m/s for either lead or lag. That seems actually like a pretty reasonable speed. But it's at least ok for now. I left some commented-out plotting code in, along with setup.R, which sets up the code to test-run the cleaning function. Maybe can discuss with Marta.
takes a first stab at downsampling the data to remove bursts. Thanks to chatGPT for this, although I'm not fully satisfied with how it comes out.
Closes #88.
