Integration between Isaura and Ersilia CLI

[miquelduranfrigola]

Hi!

We were talking the other day about the integration between Isaura and Ersilia CLI. There are two strategies, I think:

1. Ersilia is run as a CLI, producing an output ersilia run -i my_input.csv -o my_output.csv, and then this output is uploaded to the database with isaura insert -i my_output.csv (or something like this).
2. Another option would be to integrate Isaura directly into Ersilia. In this case, ersilia run -i my_inputs.csv -o my_outputs.csv --save_to_lake (or something like this) would make sense.

In principle, I think option 1 is simpler, but I leave it open for discussion!

Just a note: we had an earlier (AWS-independent) version of Isaura that was writing HDF5 files locally. In this case, we already provided an integration with Ersilia (https://github.com/ersilia-os/ersilia/tree/master/ersilia/lake). I don't think we can recycle anything from there - but I put it here just in case it is useful.
