Properly handle single-line mixed-format comments

[L1ghtmann]

What does this implement/fix? Explain your changes.

See title

Does this close any currently open issues?

Appears to resolve #66, #70, and #77

Any relevant logs, error output, etc?

N/A

Any other comments?

Tested with:

• Modified code from #66

  %ctor{
  /* https://www.google.com */
  
  /*
  https://www.google.com
  */
  
  /*
  test
  */
  
  // test
  
  //*test
  }

• Modified code from #70

  
  %ctor {
  // ...
  }

/ Multiline comment including a // line comment /

// These lines are incorrectly ignored:

int func() { int a = 3; return a; / Another multiline comment; its closing sequence will be noticed / // The line below will cause an error }

- Modified code from #77
```logos
%ctor{
    /*// }}}*/
    /*// }}}*/
}

Output (all three examples in the same file with whitespace removed for brevity):

static __attribute__((constructor)) void _logosLocalCtor_5784034e(int __unused argc, char __unused **argv, char __unused **envp){    
}

static __attribute__((constructor)) void _logosLocalCtor_f0225b01(int __unused argc, char __unused **argv, char __unused **envp) { 
}

int func() {
    int a = 3;
    return a;
}

static __attribute__((constructor)) void _logosLocalCtor_854fe05f(int __unused argc, char __unused **argv, char __unused **envp){
}
