Allow `openeo.api.process.Parameter` object as `resolution` in `DataCube.resample_spatial()`

[VincentVerelst]

Version: 0.49.0

Problem
The following script will fail

import openeo 
from openeo.api.process import Parameter

c = openeo.connect("openeo.dataspace.copernicus.eu").authenticate_oidc()

s2 = c.load_collection("SENTINEL2_L2A", spatial_extent={"west": 16.0, "south": 48.0, "east": 17.0, "north": 49.0}, temporal_extent=["2021-01-01", "2021-12-31"])

res_param = Parameter.number(
    name='resolution'
)

s2 = s2.resample_spatial(
    resolution=res_param
)

Because normalize_resample_resolution doesn't allow for an openeo.api.process.Parameter:

openeo-python-client/openeo/utils/normalize.py

Line 4 in 63ac783

def normalize_resample_resolution(

Solution

Support openeo.api.process.Parameter in openeo.utils.normalize.normalize_resample_resolution() by returning something like (None, None) in that case.
