Casual import error

[banditopazzo]

Sometimes I get the following errors with import_nist commands:

[2023-07-10T20:30:44Z INFO  domain_db::cve_sources] downloading https://nvd.nist.gov/feeds/json/cve/1.1/nvdcve-1.1-2009.json.gz to /data/nvdcve-1.1-2009.json.gz ...

If I try to launch the import again it finds the previous downloaded files and output this instead:

The workaround is to delete each "corrupted" data file and start the relative year import again
