+- [x] Print out all failed tests in a list at the end
+- [x] Use new compiler API with Compile_Result and Compiled_File instead
+- [ ] Use unix (posix? bash? ascii?) color codes for errors
+- [ ] Print golden file as green and new output as red
+- [ ] Rename to Ink.jai
+- [ ] Add -test option. -test does the same as test.exe used to do
+- [ ] Add -fuzz option to run fuzzer (add args later)
+- [ ] Add -output option to output the compiled file. Issue with this is the generated data can't be output like that. Would require serialization.
