🐧 Subset training tiles within 10km buffered grounding line 
Constrain our square training tiles to only exist within the grounded ice area (give or take). To do that, we first buffer the MEASURES InSAR-based grounding line (actually a polygon of grounded ice areas) by 10km, and then select all the tiles which are contained within this buffered polygon. Makes use of geopandas' sjoin (spatial join). Also, the re-saved geojson files appear to show some decimal differences for tiles_4326.geojson but not tiles_3031.geojson, perhaps because there has been some changes in the pyproj library or something else?
