grid to numpy array

[uliw]

Description of the desired feature
This may be already there, but I could not find it in the docs. I would like to access gridded data as numpy array. At present, I do the following:

grid = gmt.datasets.load_earth_relief(resolution="05m",region="g")
df = grid.to_pandas()
height = df.to_numpy()

Thanks for any pointers

Are you willing to help implement and maintain this feature? No

just saw that grid actually uses numpy internally
