Some warnings about qr-code-generator

[nayuki]

Thanks for providing the diagnostic information. I understand what the warnings are complaining about.

In all cases mentioned, the uninitialized variable or undefined return value are impossible by design. The undefined case is always covered by an assert(false); statement - although assertions can be bypassed, so it could be a no-op instead of stopping the program. I have extensively tested the qrcodegen library to confirm that the assert(false); code path is never triggered.

I will have to give some thought about how to fix these compile-time warnings in the most reasonable way. Maybe I'll use exit(1);, or give dummy default values, or use an infinite loop.
