Symbols in a file can't be found by address if the address isn't a full segmented address

[louist103]

Example in OOT:
In TextureFactory.cpp

Looking for gMegami1TLUT using tlutOffset, which is 0x5c80 like this:
std::string sym = Companion::Instance->GetSymbolFromAddr(0x5c80, true);
Doesn't find the symbol.
But searching for it with the fill segment address:
std::string sym = Companion::Instance->GetSymbolFromAddr(0x06005c80, true);
Does find the symbol.
