Implement a Logger class that logs to the output panel

[rjstone]

Is your feature request related to a problem? Please describe. Right now we don't use the Output panel for anything, so users don't have a very good idea what the extension is doing. It might be good to use this for something.

Describe the solution you'd like Implement a logger class and use the class to log various things to the output panel. As for what should be logged exactly, we'll just have to go through the code and look for console.log() calls to see which ones ought to actually appear to the user and look for other opportunities.

Describe alternatives you've considered Just not logging anything and leaving the Output panel empty.

Additional context Joel mentioned this in discord so I'm mostly just trying to type up what I thought he was getting at and make sure it gets into issue tracking.

Going to consider this on hold until the new language server is done.
