Terminate RGBGFX when opening a file fails
...
`std::filebuf::open`'s result must be checked, though that's not obvious.

Allow rgbgfx -r to read an infinite amount of tiles without tilemap
...
Previously, indices would be wrapped after 256 even without a tilemap;
since RGBGFX can generate arbitrarily large tile data if `-N` is not used,
it should be possible to read those in.
Of course, this won't work if a tilemap is provided, but such "big blobs"
can't generate a meaningful tilemap anyway.

Implement preliminary version of "reverse" feature

Not hooked to all RGBGFX flags yet, but good enough for most use cases
(and as a base for future development, should I need to `reset --hard`.)
