Is anyone working on this issue? If not, I will proceed

Currently, we are using Console.WriteLine to debug. Console.WriteLine may cause some issue because the target user may already built a logger for them own.

Usually, in C#, we are using ILogger interface.

https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.logging.ilogger?view=dotnet-plat-ext-5.0

So we can change our logs to use ILogger. While I started to work on this, I found it hard for the user to pass in the logger. Also we didn't use a dependency injection framework. So it's also hard for us to change.

Please carefully consider the way we use it before getting started.
