Support parameterized band/apply math

[soxofaan]

from https://forum.dataspace.copernicus.eu/t/udp-parameter-not-applied/5282:

user wants to do comparison operation with parameterized threshold

canopy_cover_threshold = Parameter.number(name="canopy_cover_threshold", default=30)
output = tree_cover_density.apply(
    lambda x: x.gte(canopy_cover_threshold)
)

but that does not seem to work
worse actually, it doesn't even fail/error

did initial triage and created (failing) reproduction test case in feature branch https://github.com/Open-EO/openeo-geopyspark-driver/compare/issue1739-parameterized-apply

[soxofaan]

What seems to happen: unknown parameters in the apply callback are just mapped on the default parameter

e.g.

• lambda x: x + offset is interpreted as lambda x: x + x
• lambda x: x >= threshold is interpreted as lambda x: x >= x

I think it traces down to the geotrellis extensions at https://github.com/Open-EO/openeo-geotrellis-extensions/blob/3b43813f6d9e4ce1cf8cba739b68c5c88ab2e7b8/openeo-geotrellis/src/main/scala/org/openeo/geotrellis/OpenEOProcessScriptBuilder.scala#L1009-L1011
