Include output sent to stderr

[ManuelHentschel]

In https://github.com/hediet/vscode-realtime-debugging/blob/6b9cb42f56b5c4f01ba4d360ea13eb5ed351e72e/src/extension.ts#L49 the extension checks if the output message was sent to stdout. Would it be possible/sensible to remove this condition or make it include stderr? In the examples I tried, the extension seems to handle output to stderr just as well as stdout.
