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.

Remove incorrect check for reversed image width

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`.)
TODOs marked appropriately.
