Feat: Integration CMIP7 Repacking Tool

[pgierz]

In the process of generating compliant CMIP7 data from AWI-ESM3, @JanStreffing has been in contact with colleagues at DKRZ for the eventual data submission.

In this context, it has been suggested that we apply the "repacking tool" as a pipeline step.

To be clarified and documented in this issue:

• Link to code of repacking tool
• Discuss approach: a) possibility of calling repacker directly from Python, b) via subprocess

The two ideas are shown below:

from pycmor.core import Rule
from cmip7repacker import Repacker
from typing import Any

def repack_for_cmip(data, rule: Rule) -> Any:
    repacker = Repacker(...)  # This is a total guess. I have no idea
    repacker_kwargs = rule.get("repacker_kwargs", {})
    return repacker.repack(data, **repacker_kwargs)

Or alternatively:

import subprocess

def repack_for_cmip(data, rule: Rule) -> Any:
    repacker = rule.get("repacker")  # Path to binary
    repacker_kwargs = rule.get("repacker_kwargs", {})
    return subprocess.run(...)  # Not ideal: probably needs Disk Input and Disk Output.
