Realistic data generators + example results data for patrols workflow

[cisaacstern]

Patrols workflow runs end-to-end but our example data is not especially visually compelling

xref #45 for a trajectories test data generator

Need to come up with a corresponding generator for events

Perhaps this implies changing the pattern of saving parquet samples directly to the repo

Agreed. I've put together this code to generate synthetic relocations/trajectories data. Will need to think on how to contain within a given AOI. Or simply seed the initial points as some 2D Gaussian around a central point. I've generated events along the track simply by selecting a random sub-selection of the tracking points and assigning a random event type from a list.

Once we generate the fake relocations / events then we can use some form of this notebook to upload to ER

@davidovichmarcos I made some updates and this seems to be working well to generate realistic synthetic tracks within a bounded polygon: https://colab.research.google.com/drive/1p3BOAMpJ0ewervvm1iSy_mzQeJWBocui?usp=sharing

See here 50,000 pnts generated within a polygon.
