Incompatibility with newer version of empy package

[dslc]

When trying to generate headers with the latest version of the empy package (version 4.0.1), compilation failed with the following error.

em.ParseError: unknown markup sequence: @); the @) markup has been removed; just use ) instead

I then found this pull request - #16 - which suggested fixing the version of the empy dependency (to 3.3.4).

I did this and it worked.

pip install --force-reinstall -v empy==3.3.4

Compilation is successful now.
