LAS2020 viral info

[mekhlakapoor]

The RO injections in LAS2020 list contain a lot of viral information, but it's currently being overwritten by the TARS endpoint. If there is no response from TARS, should we map that info from the list? This will require a slight refactor of our tars integration flow (and an update in the nsb endpoint). This would be useful because the field by which we query TARS (prep lot id) is optional in the LAS2020 list, but we probably still want to map those materials.

Only difficulty that I forsee is that there are no constraints on the string input fields so we'll need to parse carefully (for example, the "Substance" field contains virus alias (AiP) or genome name, or some other thing).
