When using `LSTrajectory.plot_trajectory(..., dem='/path/to/dem.tif', ...)` I get: ``` AttributeError: module 'xarray' has no attribute 'open_rasterio' ``` The solution is to use `rioxarray`, which will require a new dependency. Also this would be a good time to relax the UTM projection constraint since we can re-project basically any DEM using `rioxarray`
