Feature Request: Allow changing output file name

[yakatz]

The name of the output is currently hardcoded to be the markdown file name and the extension for the output format.

vscode-pandoc/src/extension.ts

Line 57 in 2e03a4f

var outFile = (path.join(filePath, fileNameOnly) + '.' + qpSelection.label).replace(/(^.*$)/gm,"\"" + "$1" + "\"");

It would be nice to be able to add things like the current date (probably straightforward) or a version/build number (harder? since you would have to track it separately).
