BEA : Handle random server-side exceptions
Some new server-side exceptions randomly appears => implement a retry on each weird received data
Despite #251 (closed), some download errors are still present (and BEA server doesn't return correct HTTP errors codes). Example here: https://git.nomics.world/dbnomics-fetchers/bea-fetcher/-/jobs/11267
An idea could be to retry in all cases, not looking on error type; until we have a positive answer from server.
