pandoc 0.2.0

• input and output path containing short path version using ~ now works (thanks, @olivroy, #31)

• pandoc_install() now works for Pandoc 3.1.2 and above on Mac as Pandoc bundles' name have changed.

• pandoc_install() works now on Mac M1.

• pandoc_convert() and pandoc_export_*() now handles filepath with space (thanks, @krlmlr, #32).
