do we cover new gdal raster api?

do we cover the newer GDAL Python Raster API introduced around GDAL 3.8–3.11

with that you can much better access band level aspects

```
from osgeo import gdal

ds = gdal.Open("image.tif", gdal.GA_Update)
band = ds.GetRasterBand(1)

band.SetDescription("Red")
band.SetUnitType("reflectance")
band.SetMetadataItem("wavelength", "665")
```
