docs: Decode a geohash on a hilbert curve as a lng/lat position
  
      Decodes the geohash `code` as a lng/lat position. It assumes, that
      the length of `code` corresponds to the precision! And that each character
      in `code` encodes `bits_per_char` bits. Do not mix geohashes with different
      `bits_per_char`!
  
      Parameters:
          code: str           The geohash to decode.
          bits_per_char: int  The number of bits per coding character
  
      Returns:
          Tuple[float, float]:  (lng, lat) coordinate for the geohash.
