pylib::FileReadString
Hi,

I believe something may go wrong with transpiling something that uses files:

```
monkeycoder.cpp:8:10: error: #include expects "FILENAME" or <FILENAME>
    8 | #include pylib::FileReadString    // NOLINT(build/include_order)
      |          ^~~~~
monkeycoder.cpp:9:10: error: #include expects "FILENAME" or <FILENAME>
    9 | #include pylib::FileWriteString   // NOLINT(build/include_order)
      |          ^~~~~
monkeycoder.cpp:10:10: error: #include expects "FILENAME" or <FILENAME>
   10 | #include std::fs::File            // NOLINT(build/include_order)
      |          ^~~
monkeycoder.cpp:11:10: error: #include expects "FILENAME" or <FILENAME>
   11 | #include std::fs::OpenOptions     // NOLINT(build/include_order)
      |          ^~~
monkeycoder.cpp:12:10: fatal error: copy.h: No such file or directory
   12 | #include "copy.h"
      |          ^~~~~~~~
```
Those includes are wrong.
