Fix ECCC download failure from April 13

[dleard]

The cas-ggircs-eccc dag that downloads the emission reports from swrs failed on April 13th because of a bad file upload. We'll need to remove the invalid 1.4kb partial file from our GCS bucket and the corresponding data in our ECCC tables in swrs_extract and then manually run the dag again to ensure we've properly downloaded the new swrs dump.

Results of exploration:

• Since Jan 20th, authenticating to the SWRS ftp has been periodically failing in 2 places where auth is required: wget-spider and upload.js
• Going back 6 months of logs, this failure never happened before Jan 20th
• After Jan 20th, the number of daily authentication failures by month are { Jan: 6, Feb: 13, March: 16 }
• We believe this is an external issue with the ftp itself
• We're reaching out to file a bug with eccc
• Our code could be made more resilient to handle these random auth failures & retry those auth points until we get a good response to try and mitigate the issue

Todo:

• This (url) => arrow function should be made async
• This fetch call should be retried until it comes back with a 200 status or fail after 20 tries
• This call to wget-spider should be retried until it comes back non-zero or fail after 20 tries

I can see the retries in the upload task. Thanks @dleard
