Issue Description

The ENTSOE API endpoint looks to be offline, with a temporary endpoint in place at the moment. We should test whether our implementation in #64 works with this new endpoint to keep things running (since the rule currently fails due to timeout)

Reproducible Example

snakemake resources/GB/gb-model/GB_forced_generator_unavailability.csv

Expected Behavior

ENTSOE data can be accessed
