[FEATURE]: Multi-location file logging.

[SeedyROM]

Problem

Right now we only log the error reason in the ~/.croncatd/logs, what we really want is to pipe the tracing messages from warn and error into that same log file as well.

Ideas

• Multiple Writers or Subscribers tokio-rs/tracing#971

@SeedyROM I am hoping for a split actually!
Logs for info/warn in 1 file, errors in another turned on by debug flag

[SeedyROM]

@TrevorJTClarke So I was thinking we have the debug flag set it shows the traceback in the terminal itself.

How about we keep that, but also always store a info/warn log and an error log. (eg. uni-5.log and uni-5.error.log).

Using the log rotation from that crate puts the current date at the end like this uni-5.log.2022.10.20
