David Korth f321fe5e65 Initial import of RVT-H Tool. 
This program will allow for managing Nintendo RVT-H Reader devkits,
including dumping existing images and installing new images.

The current version doesn't actually do anything. It's mostly a copy
of the infrastructure from rom-properties, with some changes. In
particular, we're using CMake's TARGET_COMPILE_FEATURES() instead of
manually detecting C99 support.
