fix: Properties merge in collections :wrench:

[fkroeber]

Description

This fix loads the reducer for the collection creation correctly. In is necessary when entities are defined by several properties that should be evaluated jointly. The changed behaviour with/without fix can be evaluated using the MRE below.

Minimum Reproducible Example (MRE)

import geopandas as gpd
import json
import semantique as sq
from semantique.processor.utils import parse_extent

# define mapping
# note: the texture attribute isn't meaningful but sufficient for demonstration purposes
mapping = sq.mapping.Semantique()
mapping["entity"] = {}
mapping["entity"]["water"] = {
    "color": sq.appearance("colortype").evaluate("in", [21, 22, 23, 24]),
    "texture": sq.appearance("greenness").evaluate("less", 2)
    }

# define extent
space = sq.SpatialExtent(gpd.read_file("files/footprint.geojson"))
time = sq.TemporalExtent("2019-01-01", "2020-12-31")
extent = parse_extent(space, time, spatial_resolution = [-10, 10], crs = 3035)

# define data cube
with open("files/layout.json", "r") as file:
    dc = sq.datacube.GeotiffArchive(json.load(file), src = "files/layers.zip")

# resolve semantic reference
water = mapping.translate("entity", "water", extent = extent, datacube = dc)

# plot result
levels = [-0.5, 0.5, 1.5]
legend = {"ticks": [0, 1], "label": "is_water"}
colors = ["lightgrey", "deepskyblue"]
water.plot(x = "x", y = "y", col = "time", colors = colors, levels = levels, cbar_kwargs = legend)
