Replace Console.WriteLine with proper logging

[DaleStan]

This closes #54 by replacing the calls to Console.WriteLine with calls to calls into Serilog. In cases where Yafc currently produces console output, it should not change that output.

I was briefly tempted to write the logs to a SQLite database, but decided not to do that so the logs would be somewhat user-readable. The log files will look something like this, and will be deleted is they're over a week old: yafc20240717.zip

This was prompted by #178 (comment), which made me think that it might be useful to log the transitions to and from the UI thread, along with their call stacks.

@Dorus, I used Serilog instead of Microsoft.Extensions.Logging because there does not appear to be a Microsoft.Extensions.Logging.File nuget package. If I'm wrong there, I'm happy to use a Microsoft.Extensions.Logging-based package instead, as long as it provides structured logging. That is, something where I can easily distinguish between "Disk quota {} set for user {}" and "Disk quota {} exceed by user {}".

Looks like this contains the commits of your previous PR as well?

[DaleStan]

It did. I thought githib would remove the merged commits after #194 was merged, but I guess not.

LGTM

Yes this is the default for microsoft logging too, you get a lot template and the objects logged separate.

There is no official file logger package apparently, but a quick google shows there are custom packages like this one: https://github.com/nreco/logging
