getLogFile does not account for extra variable in file name

[8bitbuddhist]

LogDNA archives stored in Google Cloud Storage have an extra two-digit number after the logDate and before the file extension. This results in archives named "[prefix].[date].[number].json.gz". Since the script expects archives named "[prefix].[date].json.gz", this causes the script to fail.

Thanks for the report. It looks like the file format changed in Oct 2018. We've stopped running this project on a regular basis so I haven't noticed. I'll see if I can get this updated while we figure out what to do with this project now that we aren't using it internally.

Hey Chris, I added a workaround as part of PR #32. I'm still fairly new to Go so it's probably not the most elegant solution. I appreciate you taking the time to look into it 😄
