Benchmarks for ELC links

[SimonGoring]

Based on discussion with @jpjenk:

1. Make sure that Neotoma endpoints (most importantly datasets, occurrences, publications and taxa) that can accept any kind of numerical identifiers can correctly accept comma separated lists of these identifiers.

2. Make sure that if an endpoint accepts ageyounger/ageolder queries that this works correctly. I don’t think it does for occurrences right now.

3. Make sure that if an endpoint accepts geographic bounds that this works correctly. This may only be relevant to occurrences right now and I have not thoroughly tested it I will admit.

4. When 1-3 are sorted, we can look into the usefulness of adding taxonomic, geographic and age searching parameters directly to the Neotoma datasets route.
