ELF64 Support Module

Mass should have a standard module that allows to write (and read?) ELF executables. This should not be part of the compiler but rather written in the language itself.

@dumblob Thank you for sharing. It is not really relevant, but that is my bad for not specifying that it will be Elf64, not the 32-bit version, which has some extra requirements.
