Add optional file protection + backup exclusion to FileLoggerable

[richardhenry]

This PR adds optional file protection and backup exclusion to FileLogger and FileRotationLogger. To my knowledge, these features are only available on Apple platforms, so the tests I've added will only run on those platforms. Maybe these features should be entirely gated behind compile-time checks? Open to feedback.

I also added flushMode and writeMode to FileRotationLogger because those seem to be missing (FileLogger supports this).

Hello, can I get the kill and background mode logs if I use this package? please anyone, help me

Hi @sushichop, do you think this would be a good idea to merge into main?

Do you think it makes sense to put these initializer arguments behind a compile-time check so that this can be mergeable? If so I could make that change.

Let me know what you think.

@richardhenry it can be wrapped in eg #if os(iOS) || os(macOS) || [...]

@sushichop Thanks, should be fixed — can you trigger another test run?
