best-available-pixel based loading strategy

[jdries]

Can we define a custom loading strategy to load a composite based on:

• distance to cloud
• closest to middle of time interval (month typically)

or not custom? Check how long it takes to load low-resolution scl band??

Can be an extension off to_mask_scl??

distances= array_apply(x, lambda x,label:date_difference(replace_date(label,15,"day"),label) min = min(distances) => 0 or 1 based on distance

first prototype notebook was created. We now follow up with creation of an actual high quality composite here: https://github.com/Open-EO/openeo-geopyspark-driver/issues/544
