High memory consumption

[irm-codebase]

Describe the bug
The module requires a high amount of RAM... which is pretty costly nowadays.
Running for small countries (e.g., Montenegro) is not possible.

Steps to reproduce
Steps to reproduce the behavior:

1. Just run pixi run snakemake -c 2 results/MNE/area_potentials_pv_open_field.tif on a machine with 16 GB of RAM.
2. Watch your computer cry and then kill off the process.

Expected behavior
It should be possible to run this process with lower memory.
This is likely possible if we use dask?

Screenshots
Request for Montenegro test file.
