Explore binary export

It might be easier for external tools to distribute cc as a binary.

One solution is to use PyInstaller:
- Copy `__main__.py` to `launcher.py`
- Run `pyinstaller crytic_compile/launch.py`
- The app is then located in `dist/launcher/*`

There is also the possibility to use `--onefile` with pyinstaller to create 1 binary, however it creates a large startup delay

I haven't looked at alternatives to `pyinstaller`, so it's something we can explore.

Once we have a working process, we could do the same for slither
