`nlmod.layers.get_layer_of_z` does not return the right value for cells above top

[rubencalje]

Code to reproduce

ds = nlmod.get_ds([0, 1000, 0, 2000], top=0, botm=[-10, -20])
layer = nlmod.layers.get_layer_of_z(ds, 10)

This returns zeros (the first layer)

    spatial_ref  int64 8B 0
Attributes:
    above_model:  -999
    below_model:  -999

while I expect this method to return above_model values (-999 in this case). I think this is caused by commit 1b07783.

Oops, that doesn't look right.

This is fixed since version 0.11.0
