GeoDataFrames.read(path2file) => GeoDataFrame(path2file)

Rasters has a nice single point of entry, which is the Raster() function:

these all work to define a raster:
```julia 
ras = Raster(path2file)
ras = Raster(rand(X(1:10), Y(1:11)))
ras = Raster(path2file; lazy=true)
```

I'm wondering if it makes sense to have a GeoDataFrame() function:
```julia 
df = GeoDataFrame(path2file)
```

it would add some uniformity across the ecosystem
