GetValFromStream uses ASSERT which is likely compiled out during release builds

https://github.com/jamulussoftware/jamulus/blob/0db554413e6311c00c81900e8af114e1527ab6a7/src/protocol.cpp#L2832-L2833

uses Q_ASSERT but they don't do anything (https://doc.qt.io/qt-6/qtassert.html) in release mode. We should check weather an if () statement isn't better suited.

I assume we need to crash in case of an invalid value?

Inspect src/protocol.cpp at lines 2832-2833 and read the surrounding GetValFromStream logic, then verify what should happen for an invalid value in both debug and release builds. The change is done when invalid input has the intended behavior without relying on an assertion that disappears in release mode.
