From the 2024-09-04 challenge meeting: a command which simply wrote (or updated?) the ro-crate-metadata.json file with the appropriate parameters would be useful for post-processing datasets.

code to build on:

• copy lookup as a module template: https://github.com/ome/ome2024-ngff-challenge/blob/main/src/ome2024_ngff_challenge/lookup.py
• use ROCrateWriter https://github.com/ome/ome2024-ngff-challenge/blob/main/src/ome2024_ngff_challenge/resave.py#L322
