Add rust_payload and fixes to allow running it as supervisor Note that the 'riscv32ima-unknown-none-elf' target is not available by default in rustc, you need a patched version. I'm also pretty sure just converting the ELF binary to raw using objdump messes with stack and heap addresses, but it seems to work fine for now.
