Unit Tests

Unit tests and regressions would be nice.

How should unit test work? Should we try to load resulting velf with something like uvloader and test bytes in memory? So to ensure relocs apply correctly, for example.

I think basic tests just involve a gold master velf and the generated velf and check that certain properties/sections match.

Ex: we fixed a bug with some layout/alignment. The test would be the input ELF, and we have a GM output velf and the generated velf. Then we just check that the offsets of the sections match and the order of the sections match.
