Utility code for the ec_modules.

Contains general-purpose functions and routines that we expect to change at a slow pace. Think of this as any other dependency in your workflow.

To use it, add the following to the relevant environment.yaml in your module:

name: your-environment
channels:
  - conda-forge
  - nodefaults
dependencies:
  - pip
  - pip:
    - "git+https://github.com/calliope-project/ec_utils.git@v0.1.0"
