Update available named features with six new named Titan Features
New Titan Features
Six new Titan lakes officially named by the IAU in May 2024
> The IAU Working Group for Planetary System Nomenclature has approved the names [Chapala Lacus ](https://planetarynames.wr.usgs.gov/Feature/16281), [Robino Lacus](https://planetarynames.wr.usgs.gov/Feature/16282), [Fena Lacus](https://planetarynames.wr.usgs.gov/Feature/16283), [Dem Lacus](https://planetarynames.wr.usgs.gov/Feature/16284), [Tibi Lacus](https://planetarynames.wr.usgs.gov/Feature/16285), and [Vaca Lacus](https://planetarynames.wr.usgs.gov/Feature/16286) for six features on Titan. For more information, please see the [Titan North Pole nomenclature map](https://asc-planetarynames-data.s3.us-west-2.amazonaws.com/titan_northpole_new.pdf) in the [Gazetteer of Planetary Nomenclature](https://planetarynames.wr.usgs.gov/)
All six lakes are visible from the flyby id `T18` and segment `S01` between `72-78` degrees latitude and `129-144` degrees longitude

The largest lake is Tibi Lacus with a diameter of 47 km and the smallest lake is Robino Lacus with a diameter of 11 km
Potential Backwards Incompatibility
Release removes three named Titan features which have previously been accessible but missing latitude/longitude data
- [Garotman Terra](https://planetarynames.wr.usgs.gov/Feature/15181) (missing Westmost Longitude)
- [Kutch Lacuna](https://planetarynames.wr.usgs.gov/Feature/15181) (missing Westmost Longitude)
- [Quivira](https://planetarynames.wr.usgs.gov/Feature/6988) (missing Northmost and Southmost Latitude)
