Implement RISCV Translation (#5)

* instruction: split arm, riscv opcodes and add registers

* translate: add minimal riscv translation map

* meta: rename `test/` -> `tests/`

* test imports

* instruction: specify arguments to RISC-V ops

* wip translations

* map_val empty

* more translations + builds now

* test: run translation from RISCV to ARM enums

* map_register use helpers

* update calls to map_register with widths

* fix move of width values

* map width

* translate: `map_register_name` with semantic meanings

Corrected the translation between registers for our 64 bit architectures.

* map width

* starting instruction encoding

* have assembly output now

* patched and assembled aarch64 add

* fix patched add example

* fixed width/segfault issues

* call syscall

* merge and working print

* print and echo tests

* basic control flow

* fix count to 5 test

* meta: add final documentation

* tests badge

 Binary translator from RISC-V to ARM written in Rust
+
+
+## Testing
+
+To get all the cross-compiling dependencies, enter the nix shell using `nix develop`.
+
+`cargo test -- --nocapture`
+
+Then run `./run.sh filename` to assemble and run the file.
