Improved logging implementation

[mshr-h]

#366
The usage is something like this.

let logger: Logger = createLogger("Verilog"); // This is parent logger which outputs vscode.LogOutputChannel
logger.info("Info message");
let child_logger = logger.child("ChildA"); // The "[ChildA] " will be added when info/debug/warn/error calls.
child_logger.info("Message from child"); // The message is sent to the parent logger.

The output would be

Info message
[ChildA] Message from child"

Example output:

@Raamakrishnan Any comment is welcome.

[info] (default): Flux capacitor is starting to overheat
[warning] (nice_library): Something went very wrong, sorry

The output looks nicer to me.

Python's logger uses getChild for generating child logger.
