Documentation CLI -modelpath

The generator CLI does not mention the expected path separators for model paths: Windows ; and Linux :. This should be added to the help.

eTrice C Generator usage: [options] files...
Options:
 -modelpath <paths>             model import paths separated by path separators
...

Improvement: The current separators are platform specific and therefore add this complexity to eTrice build scripts. It might be better to have fixed separators or accept multiple arguments.****
