Error reporting script improvements

[Athanasius]

• [ ] Keeping up with softwareVersions

1. It should treat softwareVersion as a minimum to report on, so that any later versions are also reported on. It's currently a strict equality check.
2. The script should take a configuration file for the various softwareName + softwareVersions it should be reporting on. This would enable developers of uploading softwareNames to PR a bump to the version.

This would remove any need to implement something to keep up with the latest versions of the uploading softwares, which are not always released on GitHub (so can't just use the 'latest release' URL redirect trick).

• [ ] Allowing developers to check 'their' output

It should have a mode where it writes a timestamp-named file to a per-softwareName directory with all matching, unexcluded lines (any PII elided). The idea is to then publicise the top-level of this and developers of uploading software then have the responsibility to check the contents. It would likely be run daily as the easiest way to only process new log lines is to run on the just copied file during log rotation.

So, e.g. there would be https://eddn.edcd.io/reports/by-time/EDDiscovery/eddn-errors-2021-01-12T07:07:34Z.txt with the by-time directory, and the per-softwareName ones, indexable.

• [ ] Reporting of any other ERROR lines not pertaining to specific software.

If we have some issue that's throwing an exception, e.g. #164 , we need to be alerted to that.
