Utilities: Add new utility for converting images to raw bitmap binaries

Browse source 
I used this utility to check if the possible TGA images' cases for
different origins (explictly the Y origin) are generating the same
bitmap, as I felt that my eyes are not a good-enough measurement tool
for this kind of task.
This might be useful in the future for testing other implementations so
I rather have this nice utility in our codebase.
