vscode extension output pane grabs focus all the time

The extension is fantastic, but there is one really annoying problem that I can't seems to override in the vscode settings.

If you open a terminal window while working on an ispc file and then type some rubbish into the ispc file, the ispc output window will grab focus away from the terminal window. This is making working with the ispc extension pretty annoying.

From everything I can see, it's a pretty simple change to the extension that a number of other extension authors have had to make too. Outlined here: https://github.com/microsoft/vscode/issues/32872
