refactor: remove console calls in treeparser

[lcottercertinia]

Unknown and bad log lines are printed in the console, users do not really check this.
We should come up with a better way of notifying the user about these lines.

We should probably return the lines as part of the root node as "invalid lines"

1. Then send them to the vscode output channel or
2. List them somewhere in the log-viewer ui
3. It might also be ideal for these to be sent back to us or allow the user to easily report them back to us so we can improve the parser.
