Description of the problem
The documentation for grdproject.py states that unit and scaling cannot both be set. I noticed there was no internal check to make sure both aren't present. I wrote a test for it, but I'm not getting any errors when I run it with both scaling and unit set.
def test_grdproject_unit_scaling(grid):
with GMTTempFile(suffix=".nc") as tmpfile:
result = grdproject(
grid=grid,
projection="M10c",
outgrid=tmpfile.name,
spacing=3,
unit="i",
region=[-53, -51, -20, -17],
)
assert result is None # return value is None
assert Path(tmpfile.name).stat().st_size > 0 # check that outgrid exists
Is the docstring incorrect, or am I missing issues with both of these units set.

if kwargs.get("M", unit) and kwargs.get("F", scaling):
raise GMTInvalidInput("Cannot use both 'unit' and 'scaling'.")Full error message
