Add rotated numpad variant of Keeb.io Viterbi

This is just the right-hand side of a Viterbi rev2 used as a numpad with
a few media & special keys.

You could apply the same concept to the left-hand side, but you would have
to use a 1U enter, since the 2U space would be on the wrong side.

+Viterbi (numpad variant)
+========================
+
+A repurposing of the right half of a regular Viterbi (rotated) for use as a numpad with a few extra keys.
+This is probably not useful for anybody apart from me, but I have a spare right PCB and need a numpad.
+
+I haven't included a rev1 version, since I only have a rev2.
+
+Keyboard Maintainer: [Josh Channings](https://github.com/joshch)
+Hardware Supported: Elite C
+Hardware Availability: [Keebio](https://keeb.io)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make keebio/viterbi_numpad/rev2:default
+
+Example of flashing this keyboard:
+
+    make keebio/viterbi_numpad/rev2:default:avrdude
+
+See [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) then the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information.
+
+A build guide for this keyboard can be found here: [Viterbi Build Guide](https://docs.keeb.io)
