Update dictionary to include Fw types. Some possible implementations may be:

• Associate the types with the uses of values that should have that type. For example, in the UseAnalyzer, we could say that every command specifier has an implicit use of FwCmdOpcodeType. This may be more preferable since its a step towards providing type checking for these values (would help with Tighten checking of numeric values #102).
• Store the types in the dictionary analysis. If we are generating a dictionary, then look up the types (ex: analyzer would treat the opcode specified in FPP as FwOpcodeType)
