Create documentation on the curation process for new module approval

[mlocardpaulet]

We need to have an independent expert opinion on new proposed modules.
This needs to be discussed.

The idea is to reach out to independent experts (proposed by the module proposal authors), and ask for their opinion on:

• the data chosen for the benchmark
• the metrics described an how they will be calculated
• the input file format
• the overall coherence
• lack of redundancy with other modules

the comments can be done once or on the form of a dialogue with the developers. It should be public (in the github discussions).
experts can become collaborators and contribute to the module.
We need 2 forms for:

• comments on the entire module proposal (concept, data, metrics, code)
• OR comments only on the concept, data, metrics (for non coders).

This needs to be discussed among us, and we need to make documentation.
