csvexport separator option --sep does not work

Heyo!
I am using version: **windows-0.12.2**

I have encountered the problem with the separator command line option `--sep ;`, which does not work. `-s ;` works fine. Example .bat file below.
```

:: this works
tracy-csvexport.exe --self -s ; snap-new.tracy > snap-new.csv

:: this does not work
tracy-csvexport.exe --self --sep ; snap-new.tracy > snap-new.csv

```
