Make CJamStreamer::process data parameter a reference

To avoid redundant copying.

RE: jamulussoftware#967 (comment):

is it in any way possible for you to fork my code and raise a pull request?

Looks like it's possible :)

hi and thanks!
this is what I tried as well, but it won't compile anymore telling me:

src/server.cpp:420:103:   required from here
/usr/include/x86_64-linux-gnu/qt5/QtCore/qobject.h:241:9: error: static assertion failed: Signal and slot arguments are not compatible.

i tried changing the other code (in server.cpp and server.h) as well but couldn't get it to work. could you please try compiling yourself to get a better idea of what is happening there?

Okay, I got it working. You have to match the signal declaration in server.h too. And according to this blog post, it should be passed by reference: https://embeddeduse.com/2013/06/29/copied-or-not-copied-arguments-signals-slots/ So possibly the other cases that currently pass by value are bugs.
