Dead code in the code generator

[psychon]

As far as I can see, there is no fixed size switch anywhere. Put differently, the following patch causes no problems (well, some compiler warnings, but that's it):

diff --git a/generator/src/generator/namespace.rs b/generator/src/generator/namespace.rs

                     switch,

I'm not quite sure what to do with this knowledge. Remove the dead code from the code generator?

I think I had added that thinking of #369. For example, if ClientMessageData gets replaced by a switch, that switch needs to be handled as a fixed size type because it is inside a non-GE event.
