libragephoto: improve get and serializer reliability

Browse source 
- get functions do not return NULL or nullptr anymore
- serializer checks for valid references to not crash
- tight buffers do not prematurely end writing anymore
- add zeroBuffer function for future nullbyte insertions
- IconvTest.cpp: remove some C-style casts
- RagePhoto.cpp: improve initializer reliability
- RagePhotoA.hpp: throw error when instance could not be allocated
- README.md: minor markdown fix
