Ability to specify alternative executable (i.e. panzer instead of pandoc)

[thiemo]

There are wrappers for pandoc which enhance its functionality, for example panzer.

I suggest the following feature request:

Addition of option to choose the pandoc executable

//-------- Pandoc Option Configuration --------
"pandoc.executable": "pandoc", // default behaviour, use pandoc executable
"pandoc.executable": "panzer" // use user specified executable (in this case panzer)

there are no compatibility implications, because panzer takes the same arguments as the original pandoc, and then some more.
