windows carriage return

[StephaneTy-Pro]

thanks for this wonderful tool

i use illiterate on windows in some piece of code i had a bat file but because carriage return have to be \r\n instead of \n bat execution fail

could we imagine adding a param to adjust that on element locally

instead of

```bat {export=./run_generate.bat}
REM some code
```

write

```bat {export=./run_generate.bat, cr=windows}
REM some code
```
