Convert Gemini taxon results into iNaturalist taxonomy

[sylvain-morin]

The CV results from Gemini API will return scientific names.

We need to do the reconciliation between these scientific names and the iNaturalist taxonomy.

For each observation in the Gemini results CSV file (observation ID / Gemini scientific name), we will try to find the associated iNaturalist taxon ID.

We will store the results in 18 CSV files (for each evaluation group), listing:

• observation ID
• scientific name returned by Gemini (or N/A)
• iNaturalist taxon ID from Gemini scientific name (or Not_Found if reconciliation is impossible)
