refactor: replace log with slog

[elecm]

Passing the logger throughout the code is not a good idea and it turns your code into spaghetti code.

Now, Logger is a standalone package that works globally. You can use it like the slog package by importing it into any package.

And the new logger package is a wrapper around slog, and the exported functions are the same as before, so there are minimal code changes.

import "bepass/logger"

logger.Error(msg, args)
logger.Errorf(format, args)

Alright, Thanks.
