outside the bay on jetson :)

we're not getting any covariances in the Rust code rn, so wanted to make sure that's not our fault. here's the SBF: outside_bay_feb16.zip

edit: it was our fault; the GPS receiver was misconfigured such that it only reported the most basic GNSS data; nothing covariances.

I got rid of all the extras, leaving just the GNSS data its covariances.
