    Stim compiler (#3305)
    
    This is an initial PR for the Stim compiler, which includes the setup
    for supporting the language. We still will need to add tests, better
    error handling, more language features, among other things, but the
    compiler introduced by this PR is supposed to be fully functional and
    minimally faulty.
    
    All of the code was designed around the
    [stim](https://github.com/quantumlib/Stim/tree/main) language, which is
    mostly defined by these two documents:
    
    [Stim/doc/file_format_stim_circuit.md at main ·
    quantumlib/Stim](https://github.com/quantumlib/Stim/blob/main/doc/file_format_stim_circuit.md)
    [Stim/doc/gates.md at main ·
    quantumlib/Stim](https://github.com/quantumlib/Stim/blob/main/doc/gates.md#MPP)
