First output on my RISC-V emulator!

Hi EmuDev,

I built a small RISC-V emulator that implements the base RV32I instruction set and a bare minimum syscall ABI to run simple binary programs.

Some instructions are currently encoded as NOP, and I plan to add more extensions to the base ISA to make it more useful. Eventually I would like to run a simple baremetal OS on it!

I'd love any feedback on the code structure and any helpful resources to guide me on the journey.
