Errata file for Python Recipes for Earth Sciences, by Martin H. Trauth, Springer 2022

- Page 339, replace "import gdal as gdal" by "from osgeo import gdal"

- File recipes_23.py, Line 42, missing paranthesis in "print(A[2,1])"
- File recipes_211.py, Line 1, missing "#"
- File recipes_85.py, Line 8, replace "import gdal as gdal" by
  "from osgeo import gdal"
- File recipes_83.py, Line 31, the data type unfortunately changes to
  float64 when using this function. We have to replace the line by
  I2 = np.ndarray.astype(color.rgb2gray(I1),'uint8')
